Underbody care
« on: 07 February 2022, 13:03 »
The delivery of my Clubsport 45 is now imminent. I’ve bought some VW dynamic centre caps that have already arrived, so I think my first job after the 20 mile (probably longer due to going the indirect route  :whistle:) journey home is to jack up the car and remove each wheel to fit the centre caps.

I was thinking, whilst doing this maybe I should treat the underbody where possible since it’s in the air (I’ve got a hydraulic jack) with the wheel off?

Is it worthwhile doing this? I don’t want to go mad and I don’t have any experience in this, I was hoping for something that I could just spray around (almost randomly) that will give some protection to the bits it’s meant to and won’t damage the bits it shouldn’t really be on in an ideal world?

Any thoughts on what I should use? Hammerite wax oil spray maybe?

How thoroughly will I need to clean the car if I do it on the first day, a quick pressure wash will hopefully do?

I’m sure there’s loads of advice on how to do a full and fantastic job (my TVR was done professionally before I got it), but to be honest, I’m looking to see if it’s worth the token gesture since the car is brand new and the wheels are off.

Thanks. I actually saw that last night. As he did I think, sprayed almost randomly on anything metal avoiding the brakes and exhaust.

I also looked up that product on euro carparts, think I’ll get a tin.

My thinking is that something is better than nothing and I should take this opportunity since everything is clean and the wheels are off anyway.

Dynax UC is best product to use, I have used on past 3 Golfs, I apply to everything underneath bar exhaust. I brush on, not spray as can't cope with the thought of over spray on paintwork!

I couldn’t bare the thought of spraying the underside of a new car. Genuine question - is it actually necessary?

Secondly, is there not a load of plastic bits and stuff to remove? I have removed all the lines, exhaust, tank, etc on my Jetta.

Yes, if you severely OCD like me! Give it a year or so and most painted parts will start to show signs of corrosion. I don't remove any trim. I apply with a brush.

So if you have ocd then should you not paint the painted areas first to give a thicker layer, then if you want apply protectant waxy stuff.
I know when I eventually get a new golf that's the way I will do it. Its the aluminum corrosion i don't like in the engine bay. I had tried the ACF50 at the time but limited results and it gets dusty pretty quick. A new car start to corrode/paint peel surprisingly quickly.

Probably, yes! But I have a limit and the BH Dynax just about keeps me happy.

I’ve been looking at the dynax UC, I’m ordering some as I’m also getting BH double wax. One question…. With a brush? Do you spray the aerosol in to a container then simply brush on?

I posted before in the mk8 forum, I’m new to detailing and I opened a can of worms last time I asked opinions on “waxing for beginners”  :grin:

It's a very good product, I have purchased a 5ltr, I let the whole tub sit in warm water / the sun for 30mins or so before I plan to use, then pour into a disposable container (milk carton with the top cut off is perfect) the apply with a brush, normally just get some cheap ones from B&Q. The one with the angled head is very good for getting into tight spaces as I like to ensure everything metal/painted has been coated, even bolt heads!
