I have been poking away at my 69 firebird project for some time now and keep running into things to re-do that the previous project owner thought were "ok". Anyway, I stripped the car down to bare metal and coated it with a couple coats of SPI epoxy about 18 months ago. I replaced the roof, got a new hood, replaced the filler panel between the trunk lid and the rear window, pulled some major dents form the tail panel, added length and width to the doors, etc. I did some filler work on the tail panel and the sail panel and now have some bare metal spots showing. Was gonna spray a fresh coat of epoxy, guide coat, fill low spots with Rage, and they? I have a gallon of 2K urethane primer and a 1.8 tip for my gun. Would this be enough fill if I have mainly new body panels and plan to get most of the major fill done with the rage or glaze?
