removing undercoating

I faced the same dilemma as you last Fall. I used one of these on my project. I used it for all four wheel wells. I followed up (not finished) with naptha to get the last of it off. I used a 60 gal compressor and the air tank could recharge while it was being used (not a real high air volume pig). I think that the fron aprons took me about 1-1/2 hour each. I found mine on sale and thought I'd give it a try and it was slick. Another member referred to a multi-tool..........pretty much the same thing, but not electric. L8r
