I just did mine a couple weeks ago, I used aircraft skin remover and pretty much painted the entire bay one section at a time.

It would sit for 15-20 minutes and the paint would bubble pretty good. Then i used a high pressure attachment on a garden hose and most of it pealed off pretty good. I didn't have three coats to go through though.

Anyways, i did that and just used a wire wheel to clean the last bits of stubborn paint. You have to paint it on pretty thick though and DEFINATLY where gloves. I've been around a share of solvents and this stuff is nasty. I think i bought 2 or three cans of the stuff for like 11$ a can at autozone.
