Crap Up In The Fender Wells, How do I get it off? Options

[riverman]

My PO (haven't decided if he is a DPO or DAPO yet) undercoated the car with an oil-based, tar-like undercoating in an effort to slow down Mother Rust. Not only does this stuff weigh about a 1000lbs, but it's a bitch to get off. Anything I can reach with my grinder comes off okay with a cup brush, but there are certain areas, like up in the fender wells, I can't get to. I've tried heat and a scraper/wire brush, but the stuff only gets gooey and sticks even more. I've also tried varsol, and it works on the thin areas, but up in the fenders the stuff is so thick (up to an inch) that it won't penetrate.

Short of sandblasting, does anybody have any other ideas?

it will burn your skin, even a small amount, say half a drop, maybe even a speck of this stuff, and within minutes it burns like hell, really, makes you run to the sink to cool it off.

my doctor says that if i'm lucky it might heal itself back to where it was in a year or so, if not, oh well ...

btw. you lose all sensation in that area too (kills yer nerves) ...

fun stuff ...
