If it's the yellow stuff, it looks like what we call "Zinc Primer". Anyways, your car looks awesome!!, I wish we could do that kinda work outside.
Wow, looking great. Wish we could get those door skins up here. I'd be tempted to go with the shaved door handles with remote door latches/door poppers since they don't have the holes for the factory latches. Need to get one of out American suppliers to import some. - Matt
