I'll try some of that stripper Joe - I think I'm gonna get lucky though since we flipped the body today and it doesn't seem too bad. The places with it are real brittle and flaked off with a few hits with the hammer. If all else fails, I'll take the torch approach.
We finished the passenger side wheel well extension today. Of course, more and more rust was discovered. We're going to take some angle iron to re-enforce the wheel well to bed seam. Both sides are eaten up with rust just in front of the wheel well where the main hoop mounts. We're cutting those out and going back with a thicker diamond plate steel we had. While cutting that out, we went ahead and cut out the passenger side floor pan.
Last thing we did was flip it over on a rolling stand so we can go to cleaning the bottom. After the pressure washer hits it I'll be chipping that undercoating crap off and wire wheeling again. I think I'm going to go with CoachBarnes advice and use
Liner X-Treeme off of ebay on the under-body.
Here are a few pics from today.
