    Breakthrough on stripping undercoat

    OK, best rough method is heat gun and scraper, but getting the residue off was being a problem. Paint thinner, lacquer thinner sort of work, but highly volatile. Don't care for using gas as a solvent.

    PB Blaster! Works like a charm. Does not evaporate too fast so it can break it done. Wipes off. Then you have to just wipe it down with thinner before painting. HUGE advance. Great now I am down to just one inner fender!

      For me the wire brush was impossible, it throws it everywhere and makes a hell of a mess. Eventually I used one of those oscillating tools with a little heat from a heat gun, peels off a treat.

        Yes i know it makes a mess,like i said not the best job to do,but its quicker,the trouble i found with heat gun ,it melts bits that land on your hand it takes you a miniute to relize your being burnt and then you cant get out from under the car quick enough oh the joys of a Stag

          I guess a wire brush works on some of the older tar, but not on softer rubberized undercoat. Anyway, my post is for getting the residue off. Heavy stuff I use a heat gun and putty knife. The only method that worked for me. Don't have to heat enough to melt. Just soften a bit. Heat about a square foot and let it soak in so the metal is warm. Thin gloves help. I tried a scaler, power chisel, and an oscillator. None were any help. Taller jack stands were a big help ( 6 ton type)
