Ok, I finally got my new cowling fitted, drilled, and trimmed. I sanded it all over with 320 paper and got all the shine out. I have Rustolium primer for general use. I tried it on a test piece and it seems to stick well and is flexible. After 3 hours of curing, it does not seem to be very tough (I can easily damage it with a screw driver). I hope after 24 hours, it is tougher. I plan on spraying LusterKote for my top cote. I don't need a concourse paint job, just a durable one.

Will I have success? Should I use a different primer? If so, why?
