    What kind of undercoating will keep the frame from rusting?
    What is everyone using?

    Everyone here trusts POR15. You should put that not only to the frame, but to the entire underbody. Try <a target="_blank" href=http://www.por15.com>www.por15.com</a>

    Well POR works well but you need to sand down the frame to bare metal. Eastwood has some stuff for frames that is pretty good from what I have heard, but never used it. I would personally just hit any rust starting on the floor boards with it after grinding/sanding the worst stuff off. I did POR under my truck originally when I got it, to keep more damage from happening. I just got the floor fixed in a couple spots that were bad before I bought it and used Zerorust aerosal spray cans on the bare metal. Much cleaner then brush on IMO.

    Hit the rust areas with your choice of stuff...ZR, POR, etc. I nailed the under side areas that were painted and no rust with Restoleom gloss black... s coats and them used a cheapie $2-3 a can undercoating on decently thick. IMO remove any rust if possible... treat the area, and then layer, layer, layer. That's my $.02 worth oin dealing with MN salt

    I am a child of the eighties and The Transformers will never die in my heart. It's Jazz, by the way. [​IMG]
