tried heating the undercoating stuff first, but it doesn't make it any easier to remove. heating it goes from gummy to exothermic, with no real in between phase that makes it easy to remove. so... i had a few more fires this evening.

on the positive side, i don't get fumes (from the fires), since the fires are underneath the car, and i'm working inside (and today, a nice light breeze kept the fresh air coming).

i brazed on a few more patches. i'm maybe half finished the welding now. it's getting a little easier too, though i certainly suck by pro standards.

i read a small college welding course manual last night that helped me to refine things a little. i didn't make any holes, and had better luck doing a continuous braze as opposed to a bunch of spot welds.
