1969 Frame Off Body Preparation Question

[Steve M.]

• I am doing a frame off on a 1969 convertible. The original color was Riverside Gold. The car will be painted with PPG lacquer. I have stripped the car down to red primer with Kleen Strip for Fiberglass. Red primer has been removed on the rest of the car with 3M Green pads and water. The right front fender was replaced in the past. I have sanded the 'filler' with 220 grit sandpaper and removed most of the filler. It appears that the filler was applied to cover the fibers in the fiberglass. Some of the fibers can be felt and appear to be rough while others are covered by resin and can still be felt. My questions are how to fix this issue after I remove the remainder of the filler? Should I apply PPG 2 Stage Epoxy? or Use Feather Fill or Slick Sand? Or follow some other course to prepare the body for paint. Any and all comments or suggestions will be appreciated. Thanks Steve

I don't have that much experience with fiberglass but I think I'd go the epoxy primer route. In my experience nothing sticks as well as epoxy primer and its a nice stable foundation for any paint job. Then I'd go with a couple of thick coats of poly primer like slick sand/feather fill then block it and see where you stand straightness wise.

I have used the DP series of primers my last few projects and I am very pleased with the results on both metal and fiberglass. PPG claims that the DP series also acts as a sealer before color coats. So far no shrinkage or soaking( 2-3 years).DP also has some colors available (74) is their red oxide. 90 is their black and looks very correct and has performed well on frames against gas spills etc. Hope this helps.
