Thanks for posting the pics dude! You have your flicker on lockdown or else I would have already popped them on here. That J20 looks awful similar to one from the wayback files. Not quite as "school bus" yellow as Bill's was. I'm curious to see the longhorn too.
Oh and I wouldn't stick you with the bodywork. Well at least not all of it! My best thought is to fix the minor spots in the floor first and shoot it with primer and Hit it with this stuff.
One of our college buddies used this on his Jeep tub and raved about it. Much much better than the duplicolor stuff Bill used. The rest of the reviews I've read were positive as well.
