Glad to see others are getting in to what I did years ago, but no one listened! I use Krylong Automotive, about five bucks a can, AND HAS AN EXCELLENT SPRAY HEAD! I then CLEAR COAT IT WITH MINWAX POLYCRYLIC in the spray can. I tested these years ago with 25%, left standing 24 hours with no problem. I did a rub test after 8 hours, no problem. By then you have cleaned your plane, gone home, have the steak on, and have downed a few! Here is the deal, you must let the paint cure for a couple of days. Then a coat of mist of the poly, cure for a couple of days, one more coat to cover, let cure for a week. Yes, I know, long time. However, you will have a great paint job for about ten bucks that is resistant to just about anything but Godzilla. You have to remember that the poly is plastic. No, for you all that won't take the time to learn this, the poly will not yellow. It will last longer in the sun than you will. Oh, Rustoleum is good, but I think Krylon is a harder paint, the spray head is better than any. OK, NOW YOU CAN HELP ME! I have Air Force numbers for three different shades of gray. Where do I find some matching numbers so I can get the paint mixed at the store? Thanks Tons!
