OK... a few things here...
1. clean and degrease before you start painting. I'm noticinga little bit of "fish- eying" This is caused by the surface tension of the paint being stronger than its bond to the surface... caused by a dirty surface.
2. PRIME!!!! ALWAYS prime your surface... the primer creates a nice surface that increases the bonding ability of the topcoat paint. A good primer coat is VITAL to a good paint job.
3. Hold the spray can farther away... 12 to 16" is usually good, and spray in even strokes accross the piece, not in circular motions. Start spraying off to one side of the piece, and spray all the way accross off the other side. This helps to ensure an even coat.
4. check out the paint guide in the installs forum for step by step instruction, and if you have any other questions, PM me!
P.S. i would sand it down smooth and start over
Good luck, and keep us posted
