The Eccentric said:Hatch, I've used Testors Enamel- it is notorious for slow drying times. When they say recoat within 3 hours or after 48 hours they're not kidding. I've had many a coat wrinkle and I've had them still tacky after a week! If I recall correctly uv light will help cure faster and a warm, dry environment helps, no wind to blow dust on the tacky finish. My best looking paint jobs are enamel but they were the hardest. There is a lot of info online about this topic. Thin coats also help to fully cure.
Puma- yep, Rustoleum is a joke! It's got fish oil in it to penetrate the rust, had cars with oily splotches before. I use Dupli-Color now but I'm starting to like the idea of the Big Dogs sharpie method.
I switched to Testors or Model Master lacquer for that very reason. Dry enough to handle in less than 30 min. They sell a high gloss clear coat that I like also.
