I am repainting a rocket and having problems with the primer adhering. Any advice would be greatly appreciated!
I originally primed the rocket with Rustoleum Filler Primer and then top coated it with the Rustoleum Bright Coat Metallic Chrome. It looked great but the paint was not durable and was constantly getting damaged and picking up finger prints. And then the rocket itself got damaged and need a repair, so I decided not to repaint it in the same problematic paint.
I did my repairs and then sanded the chrome paint off. This stuff was a real pain to sand! The dust had an almost sticky feel to it even after it had cured for 2 weeks in hot, dry conditions. The sticky dust fouled the paper immediately, so I went through a lot of sandpaper. Also, as soon as the sandpaper touched the paint, any scratches in the chrome finish looked the same gray as the primer underneath it, so it was very hard to tell if I had sanded down to the primer layer or if I was still in the chrome layer. And finally, in the area of the fin fillets, the paint did not seem to want to sand at all. These are not big round fillets, so just getting the paper into the sharp corner is a bit of a pain, but it also seemed like the paint was just tougher in that area. There were a few spots where I could still see the chrome, but they were very small.
I decided to use a primer that I have used before on glossy surfaces roughed up with sandpaper --- Zinsser Bulls Eye 1.2.3 Primer For All Surfaces. It worked OK everywhere except for in the fillet area where it left what looked like a narrow crack right in the fillet area where it had been hardest to sand. I guess the primer pulled away from the chrome paint that was left in that area. I let everything dry overnight and sanded it smooth, then shot it all with a fresh layer of Rustoleum Filler Primer to try to fill the "crack" in the fillets.
Now it looks like it is kind of bubbling up in that fillet area! Anyone have any suggestions? I'm planning on sanding out the bad spot and hitting it again with a primer, but does anyone have any suggestions on a product that can really stick to anything? Is there anything else I can do? I am running out of time on this rocket!
