Just thought I would let everyone know.
Bought one of those osciliating tools from Harbor freight, put on the scraper blade and tried going after some undercoat. It does pretty dang good.
It basically will pull the undercoat off as a sheet, leaves some residue, but its enough to be easily gotten with a wire wheel. On flat portions of metal it pretty much leaves the underlying paint intact (does damage it some though). The blade is flexiable enough to do the majority of the curves (will damage paint in curved areas).
Works best on areas which you havent put a flame too yet. Be prepared to resharpen the scrapper blade.
Ive tried pretty much eveything but sand blasting the undercoat, and its my preferred method. Its probably a little quicker then a torch and scraper, but no fumes, and it doesnt fling the undercoat everywhere like a wire wheel on a grinder.
Here is a link to the tool I bought (yes I bought the cheap-o Fein Imitator tool).
