just gone to change my back box and cleaned the gunk off the bottom of the car and uncovered a few rust patches around the exhuast channel think this is becuase my heat sheild is missing, now Ive rubbed it down to remove the loose rust and treated it with co-rust and was going to bang a coat of waxoil onto it, but I am a little woried due to its location next to my exhuast it could be a fire risk?
anyone used it before and is it safe
-
Waxoyl, not a good idea too close to an exhaust for fire reasons, but also, the heat generated by the hot system will eventually dissipate the waxoyl, best bet would be to give it a shot of aerosol stonechip protection...

I would not use it near an exhaust.

so what do vw use and body shops? as dont want to have to keep getting under there and painting it every year? they must use some kind of underseal that doesnt cuase problems with heat, and lets be honest the fuel tank is plastic and not a million miles away from the back box

Yes but the stonechip stuff they use has a heatshield over it.
Maybe look at refitting it.

What Thom said.
I'm sure he knows considerably more on the subject than me but I've had the whole underside of the car covered in Dinitrol 4941 for 2 years. Never had a problem.

Epoxy mastic is one of the best things you can paint on the underside of your car. Follow it up by a Dinitrol product.

The £25 starter pack goes a very long way.
Forget Waxoyl and Hammerite it's sh*te
-

if it's wax... heat it then remove it :rolleyes:
-
tried that aswell with the hot air gun and its not melting, it apears to have just seaped into the vw underseal and dried, think im just going to have to leave it on
-
if it's not melting then it should be fine near the exhaust anyway :smiley:
-
Is Dinitrol really that much better than hammerite products?
-
I've always found Waxoyl products difficult to apply and almost always need an annual 're-coat'. Hammerite paints sucks on anything that is exposed on the underside. I've used POR 15 paints which is much better than Hammerite but still doesn't last long. Now using Epoxy mastic on the underside and as base on any repair work and it takes some beating.
Dinitrol chassis and cavity wax products always apply better and last much longer than Waxoyl in my experience.
-
So what dinitrol products do i want to buy then?
-
POR15 is great but a real PITA to prep for. Also £££ and once the tin is open you have to use it.
You are going to want 4941 for the underside and 3125 for the box sections although I have to say I prefer applying the Bilthamber dynax cavity wax. Make sure you get a long extension spray tube to reach right down the sills etc.

Usually these, covers most jobs on the car.

I like to use the underbody (4941) wax on the surfaces, I find with waxoyl it tens to dry up and crack, this stuff doesn't and kind of self heals.

With POR 15 unless the surface is perfect it peels off after a year or so.
-
Nice one, i'll look into it :smiley:
-
It says they do 1lt tins would these be better ?? also how many cans would be needed to do all underside ??
-
I did all the arches on my 911 with 3 cans and have some left for touching up, must have some coverage as the inner arches are quite large and exposed so a lot of surface area. If you are just doing one car I'd buy aerosols as it would be easier and wouldn't cost much more compared to the convenience.
-
Yer i recon about 8-9 cans then ??
-
Sounds plenty to me, might be worth looking at those kits though.
