66 dart convertible

Yeah I get a copper pipe from hardware store and beat it flat with a hammer and stick that behind what I am welding. It acts like a heat sink to keep the metal a little cooler. And weld does not stick to it. Really helps a lot.

Those door gaps look great. I like to let the high build primer set for a week and then block. Gives it time to settle. That way when you paint it sand marks don't show up later on.

yup using the copper backing I pop riveted it onto a handle because the darn thing got HOT! the only problem I really have is that I have to plug weld so many of em, of course it exactly how many I had to use a spot weld cutter on. yeah the gaps look pretty good on the body cart and even better when I put it back down on jack stands where the wheel would be. I only have the first coat on it now and have found a couple of places that I did less than stellar body work and the wife's car is getting a new trunk lid so I get her old one which is 3 times better than mine but still has rust on the bottom edge. I'll fix those first and then put on the second coat of grey/gray hmmm i like gray (sp). The car is going to be painted "cool vanilla" from ma mopar color chart so I''ll be shooting 2 or 3 blocking coats in Buff primer and let it sit until I get the money flow to get the paint right before paint I'll block it and seal it, then jamb it. wait a week or so and then scuff and shoot (hopefully all in 1 day so I won't miss my recoat window)
