I'm thinking about treating the slight rust under my car and painting it, seen a few people have done this just wanted to know what products they used or there are any guides about? Probably going to focus on the boot area and the arches to start.
Protecting the underside of the car

#2waxoil is the best stuff imo
-
#3Clean the living shit out of them, then wire brush all the rust off and give a good coat of wax oil
-
#4i think you can get proper underseal stuff, looks like tar lol.
-
#5i no wt ya mean i used some it was like bitchumen or sumat i think, in a spray can and was jet black and bit gooey haha
-
#7I use waxoyl and apply it with a paint brush. Does a good job IMO
-
#8Waxoyl is spot on imo... doesn't look pretty, but spray/ 'paint' on and forget - function over form and all that.
It doesn't really add too much weight like paints/ heavy duty underseals can. Can be removed with a strong degreaser and elbow grease too. -
#9i seen it in someones progress thread. cant remember who's though.
-
#10with waxoyl, can it bee sprayed on where ever without giving a funk?
-
#11This is the clear stuff.

If you do your wheel arches with it, the shit/ muck does stick to them over time... you can strip them back and re-do them every year if you're a style whore though.
You need to keep it away from brakes - I cover them with a carrier bag when spraying it on. Try and keep it away from exhausts too unless you like the smell of burning lol.1 user thanked this post:
