This question was my first post but never showed on the forum so I'm asking again.
I am repainting the area above the windshield on my motor coach due to peeling clear coat.
I sanded off all the clear coat with 120 grit, followed by 220 and feathered with 600 grit. Some of the base coat sanded off to expose the gel coat.
I'm painting with 3-M Diamont. Base coat is the same color (brown) followed by the clear.
Do I need to lay down a coat of primer-sealer? Or can I spray my base coat directly on the fiberglass surface I have now?
I do have a can of Eastwood 2K Aerospray Urethane primer I could use. But it's a rattle can and I'm not sure I will get a good even coat with it - so it may be better to not use this on such a large surface. I don't mind buying 3-M DP20K urethane primer if necessary, but that would cost me another $200 and of course I don't want to waste my money if I don't have to.
