Re: undercoating

Heat gun and a scraper is what I've been told.

Re: undercoating

I used some odd rolac type discs. They were not the sand typeI used 2 different ones. 1) looks like it has a bunch of fingers sticking out. 2) looks like a piece of scotch bright filled with a wax type material. these worked great. good luck

Re: undercoating

I like using the 3m paint and rust removers.

The first one would work best for removing the undercoating. You can get them alot cheaper at walmart, usually.

I've found they work best in a air powered tool rather than electric.

Re: undercoating

Heat and a scraper will be the cleanest. Comes off in chunks, often leaving perfectly clean metal. Key is to SOFTEN the stuff, don't melt it.
