Ok I thought I'd post this in the mk1 forums since I figure maybe more of you have experience with this. I have a mk2 that's in really good shape. No rust under the car at all. But some of the undercoating is peeling off. Anyway I wanna re do the whole underside of the car. Rust-proof/seal it. But have no idea what to do or what products to use. I was thinking it would make sense to fully strip all the undercoating off first and start from there. But I have no idea what to use to get it all off. And what do I lay down as rust prevention? Or if tere is a progust thats basicly the same exact thing that vw uses at the factory. I'm pulling all the subframe and rear beam and all stuff under the car so I'll be re doing everything else as well.
