I'll second both of those comments.
When in doubt, put another coat on
. You'll thank yourself if you ever try to peel it off, as well as if you're trying to scrub bugs off or anything.
If you haven't started already, here's a couple application tips.
For your first coat, don't cover. I'm talking like 40-60% coverage, real light. Let that dry before continuing with your next coat (which I would then consider the 'first' coat). This will help with adhesion, though it's not catastrophic if you don't do so.
Don't apply too much with one coat, or you'll have runs, which are really hard to repair without starting over. Take your time and have some fun. (I'm sure the guys would suggest doing this with a beer.)
If you have any other questions be sure to ask. I-- or many others-- can walk you through how to make clean stripes or whatever you want, most likely.
Be sure to post pictures of what you're done!
