Removing undercoating in prep for welding

Okay, so I might've just screwed the pooch on this one; but, I placed an order with Eastwood and didn't get their undercoating removal system. I figure it's been done plenty of times before, without Eastwood's help. So, how did you guys do it? Keep in mind I don't need to strip the whole car, only a section of the floorpan underneath the car.

Thanks!

I've heard of lots of ways, but the most common is a heat gun, a scrapper, and lots of patience.

If you have the access, a propane torch (or similar gas) & scraper works pretty good too. Once you get the majority off, laquer thinner (acetone, gas..) & a rag can clean the rest.

Just don't try using both at the same time :nono: :sillylol:

Haha, oh man, that would suck... thanks for the tips, guys! Luckily I don't have to strip the whole damn floorpan.

Ha, when I welded on my SFC's I used a 40 grit sanding disc on an angle grinder -- 3 minutes -- done!

EDIT: after the welding, I made every thing look pretty with some rattle-can undercoat
