I have a couple of pieces to paint on the interior of a 1969 Shelby. Two of them are metal and the other four are plastic. The plastic pieces are fairly rigid and float so I will use adhesion promoter with them. Since the color is an off white my plan was to use white epoxy primer as a sealer 1/1/1 and then top coat with the interior paint. The problem is that all I can find is rattle can lacquer in an interior color/shine. The local PPG supplier doesn't carry interior paint anymore and the Axalta supplier is out of one of the components needed to mix the RTS interior paint which happens to be almost $300 per quart. So if I have to use the rattle can, how long do I have to wait after the sealer epoxy before spraying the lacquer?
