    Started a resto on my 1981 Z28. Anyone have a good way to clean up the sealer the factory used on the firewall? I heated it and scraped most but what is left is a real pain to remove. I was hoping to find some kind of solvent that I couple clean it off with, then scuff and paint. I would rather not strip it down to metal. thanks Rick.

    Quickest & easiest is with a wire wheel on a grinder. Don’t know of a solvent that would work without soaking.

    Just a safety note. I use my Black & Decker 4 1/2 in grinder, it will really spin a wire wheel fast. I've had one of the wires come off an stick in my cheek/face. I now where a full face shield.

    There's no easy way to do this short of sand blasting or chemical dipping. Doing this any other way is work for sure, I just did that job a few weeks ago. Best thing I found was a heat gun, hand scraper, and then cupped wire wheel on a 4" grinder in that order. As Larry said make sure to use eye, face, and body protection because wires will be randomly flinging about.
    If you're taking off the old you will want to replace it with new seam sealer, otherwise you will be open to moisture seeping in between the panels.

    I use 3M Rolocs on a 90 degree die grinder. Makes short work of it. No wires to pick out of my arms/face either!
