i know the paint is soft on the mk7,but I literally come back from shopping with nothing on the car,came back out 10mins latter to get some more bits out the boot only to find a nice splattering on the roof which had already baked on in the sun ,I quickly grab some Maguires spray detailer to loosen the debris & gently removed it ,but to my horror it had etched into the clear coat, I then tried to polish it out but to no avail.I don't remember my TR mk7 gti being so bad , does the clear coat get harder over time.

I had a similar issue today. Had a squad of giant seagull replicate the scene from pearl harbour all over my GTI today. ( detailed it 2 days ago for its return on Friday when I collect my R). I sprayed it and wiped, but had to repeat before it came off, but that was baking in the sun for a good hour. My GTI is 14 months old and seemed pretty resistant given in was 19 degrees here today
-
same thing happened to me just last week,
less than an hour on my roof and its attacked the clear coat. I tried to polish it out but no difference.
Like all these things, it bothered me for a while but tbh i can only see it if i look for it.
My car is nearly 2 years old so i'd say its cured by now..

It doesn't etch your paint... http://www.autoglym.com/news_articles/new-research-dispels-myth-of-why-bird-droppings-damage-paint
The lacquer can be fixed with a heat gun https://www.youtube.com/watch?v=guk5m6lcGRc&feature=youtu.be

With the Autoglym explanation given, surely the lacquer would "heal" itself after you'd removed the sh!te and the car went through its next heating/cooling cycle sat in the sun, flattening out the lacquer again after it had softened in the heat? Unless the pH of the stuff is part of the reason it happens, coupled with the application of heat in the sun. Can anyone say they've had bird sh!te etch their paintwork and know the car was in the shade the entire time from deposit to removal? If so then it would disprove that theory.
No mention in their experimentation of them doing a "control" test for paint damage with the application of contaminants on a cool car to determine that hot bodywork and the moulding of the soft and warm lacquer is the prime reason for paint dulling
I haven't had any etching with C2V3 applied, even if I haven't promptly removed bird sh!te from my bodywork and the car has sat in direct sunlight getting warm, and yet this explanation claims that sealants have no preventative properties and that moulding around the dropping will occur anyway and marr your paintwork.
Definitely not my experience, and if that is the case then surely Mr Autoglym is doing himself out of a job? If these sealants offer no protection against bird lime or other contaminants with a high or low pH, then why bother if not only for protection against UV fading (which you'd expect the clear top coat to afford some protection against)?
I remain a cynic of the conclusions drawn by their experiment.

Did you watch the heat gun video?

I watched the video - just because the paint recovered under heat does not prove the Autoglym theory, it just means that under the application of heat after cleaning, the clear lacquer can behave like a liquid and fill from the surroundings and then reflatten, whether it was scarred on the surface or cratered. That's no bad thing (if you are careful with the heat gun and don't overcook the lacquer).
I've always found that on a well sealed car, as long as you make sure the bird sh!te is fully moistened before you remove it then no etching or marring occurs on the lacquer surface.
He's taken the heatgun solution, thought of one possible explanation and provided it as proof. If he were doing a proper experiment, he should try careful removal of moistened and softened lime that has cooked in the sun, same for lime that has dried in the shade on a cool car - doing it for both a sealed and unsealed surface and see what damage lurks on the lacquer surface under all 4 test conditions.
I certainly wouldn't take his testimony as "proof" that bird lime scarring is unavoidable (but fully reversible), so no need to seal your paintwork to protect it against bird lime.

Not in any way saying you don't need to seal the car, was simply saying that bird poo doesn't etch your paint. That is a mate of mines car that is immaculately looked after. Prior to trying wet sanding (on the etch theory) he tried a geat gun and it worked.
Essentially all I was saying is if there is damage caused by bird poo that has been left, the heat gun sorts it.

I have visions of MH trying to net a seagull and then squeezing it to create a test sample just so he can upload the control test to win this discussion :)
Sorry MH :)

I've already been up on the roof to try and snare one, but the wind got up a bit and it just wasn't worth the risk. :whistle:

You should come here, you can't move without tripping over them :laugh:

On my mk 6 DBP GTI, a bird shat on the bonnet first thing in the morning, sometime after I'd parked up. As it was summer, and on one of the odd boiling hot days we had, by the time I'd clocked it at lunch it had 'burned' through the paint. I had a professional try everything to get rid of the 'stain' (hand print size) but the mark was always there. So, a heat gun didn't fix it. But maybe I was just unlucky and that bird had a madras the night before, who knows! #japaneseflag :laugh:

Sorry to bump an old thread but this has happened twice now to wifey's GTD which has "special solid paint". The paint is woeful - scratches and swirls if you look at it.
Anyway, 2 lots of birds poo have been removed within 10-15 minutes and yet both have etched the paint. Is this paint different to the old solid paint which seems pretty resistant.
Is a machine polish the only way to get rid of the etching ?
Yes. You'll be wasting your effort and time trying to do anything with them by hand in my experience. 30 seconds with a DA and they'll be gone. Best tool I've ever splurged on.

The paint shouldn't make any difference as it's all got the same clearcoat which is what has been etched.
As Joe says, trying to hand polish it out will be a battle, much easier with a DA. That said, I had various bits of bird poo etching on mine and a couple of those even challenged the DA, but a bit of persistence and it was gone.
-
What is a DA? I know some say it's a waste of money but I had the GardX treatment from new and the bird cr@p seems to come off without leaving a trace. So far.

A dual action polisher.
In my experience, no wax or sealant will prevent this problem. Leave bird crap baking on the bonnet/roof on a warm sunny day and it will leave a mark that only a DA will remove in my experience.
Not really an issue in the cooler / wetter months obviously.

Thank you. A challenge for chemical engineers to come up with a more resistant finish.

Speaking from experience as I live in Cornwall. You don't need to catch a seagull (aka 'beach chicken'). Just clean your car, they seem to hunt down clean cars in my neck of the woods to crap all over for sh!ts and giggles. We need to start a cull I think. :laugh:
-
I had a direct hit on my bonnet after I had the work done by the Detailer and before I had a chance to get rid of it it rained overnight and it washed it off. I never knew that it could damage the pain in just 10 minutes.

It's lethal stuff and the acidity of it (whether it etches or not) can very much depend on what crap the birds have been eating. Lots of seagulls round my way whose diet means that it etches within minutes of hitting the paintwork. I came out of work on Thurs to see two seagulls stood on the roof of my car in works car park - they patrol the place worse than traffic wardens, lol - and had sought out the cleanest car in the entire car park, lol. Fortunately they hadn't left their calling card this time, phew!
-
Lets start a petition to cull seagulls... Oh and pigeons as well! :smiley: They seem to artex my car more often than sea gulls lately.

The bonnet / roof of a car can get baking "fry an egg on it" hot even on a moderately sunny day. Bird crap left baking on that surface will make very light work of whatever magical sealant you've on the car. The heat is the big factor, as the crap really bakes on and hardens. You'll generally get away with it on a cooler / damp day. And the etching will be much more visible on darker colours and on the flat horizontal surfaces (bonnet / roof).
A DA is a really useful tool to have in the shed for this type of thing (and the usual dreaded swirls, etc). It's easy to use and makes very light work of correcting these issues. For the last few cars I've bought, I've brought them to pro detailers when new to get ceramic sealants applied. TBH I don't think I'd do it again as I'm very skeptical as to it's benefits beyond the first few weeks it was applied. Purchasing my own DA has been a far more worthwhile expenditure.
-
I keep some quick detailer and microfibre cloths in the car to deal with any bird poo that gets deposited on my car. You still need to get it off the paintwork sharp-ish to stop it etching the paint, but by soaking the poo with QD and when softened, wiping it off carefully, it's not left to bake on the paintwork to do it's damage.
When I had my mk6 GTD, it got dive-bombed in a restaurant car park on a warm sunny by what must have been a flying elephant. By the time I came out, the elephant poo had baked on hard and was more than my QD and microfibres would've been able to handle. I washed it off as soon as I got home and the paintwork was badly etched :angry:. Fortunately, a bit of effort with my DA polisher sorted it.
Not cheap, but my DA was one of the best investments I've made for keeping swirls and etching at bay on my car. My brother was really impressed recently when I sorted out some etching on his car that was caused by water dripping from a concrete multi-story roof. Looked as if it was beyond correction, but the DA soon had it sorted!

They're not that expensive tbh. I've a decent one that cost less than £200.... it's a tool that should last years and pay for itself over and over.

I suppose it's all relative Joe. £200 isn't a vast sum of money, but it's a fair bit more then I've paid for anything else in my detailing arsenal. Having said that, I wouldn't be without it, and I agree it should last years. In the 3 years I've had mine, it has already paid for itself :smiley:.

I managed to get a Das6 pro for £99 on a DW group buy and it was an excellent purchase.

I use that - its good stuff, easy and quick to apply to a clean car.
-
DA is a great investment and good for tackling for bird etching, but really need to use it for more than that to make it a worthy investment, and get your money's worth. I wouldn't be without one.
In terms of sealants and DAs, for those with coatings on their cars, worth bearing in mind that unless you have Gtechniq Cystal Serum on your car, any other ceramic, nano or glasscoat base sealant will be removed if you polish it with a DA. Crystal Serum, which is pro only application, can only be removed with wet sanding, but not the case with other coatings, even if pro detailer applied. So if in removing your etching you will also be removing your basecoat if you have one.

It's the new exo ceramic stuff on mine. Haven't a clue what it is just mine was one of the first to have it applied from my detailer. It's fantastic as all I do between proper washes is jet wash the crap off 😁😁

I had a sh!tehawk do the biggest keich/jobby on the roof of my car at work.Strangely enough it was the hottest May day for many years.Must have been about 20 deg.
It had set like a double fried egg,like concrete.
To make matters worse.The gull had obviously decided to sharpen it's beak in a semi circular motion.A nice fine arc of scratched paint.
I moved my car to another spot in the car park after that.Then i found out from others that the gulls were targeting certain colours.Grey was one of them!. :angry:
-
Not that I promote animal cruelty. But an local myth suggests feeding gulls (aka beach chickens) alca selters would the trick. Apparently they explode? :whistle:
Although I suspect being the jerks that they are, they would probably choose to explode all over your car, making the situation of this thread even worse...
-
I always carry a pack of Autoglym bird poo wipes in the clovebox in the Golf and Beetle especially for incidents like this. They're not the complete answer but handy for a short term solution.
-
I'm seriously loosing my sense of humour with bird mess now. It's every day; this morning was 6 separate areas of poo which are easily the size of goose s**t. The roof has areas of dirt from their feet or feathers where they have obviously taken to roosting on my bloody car! It has got to be pigeons, they're everywhere around here.
I should have taken photos for your viewing pleasure (or not) but I was obsessed with removing it all.
I can't see how I can stop them from doing it, seriously, it's every day.
-
Maybe suspend a cat above your car? But then that would probably mean the cat would poop on your car instead. Seriously though, I feel your pain. There is nothing worse than looking out of the window to see a massive pile of bird poo baking in to the paint work of your pride and joy, especially just after you have slogged away cleaning the thing prior to the incident.

Haha, yeh cat poo stinks too. I love nature, but not their crap on my car :sick:
-
Is the car left all day? If so, why don't you put a car cover over it. Wash it off when you get home, ready for the next day...just a thought especially if they're using your car as a toilet.

Car covers unfortunately can shift around a lot whilst on the car causing swirls, so it might be a solution to bird poo, but causes it's own problems. :sad:
I had to wash my bonnet again today after it got hit by the overhead flying crapmeisters, whilst driving along. The entire was panel covered in the stuff, grrr.

As nano/ceramic coatings go, it's probably the best one out there in terms of resilience and durability, and should be telling that it's the only coating that cannot be machine polished off, instead it can only be removed by wet sanding as it bonds with the paint at the substrate level. It's purported to last 7 years but whether that's true, who knows, as most enthusiasts have probably long moved onto their next car before having chance to find out. I know of a quite a few with Crystal Serum on their cars and although it won't stop swirling etc completely (nothing will), by all accounts it does offer some level of protection against it, which others such as even Crystal Serum Light don't really do. And it should repel the dirt (especially coupled with Gtechniq Exo) well thus helping with regular maintenance washes.
