I would recommend against doing multiple coats quick. I generally leave mine a whole day before a second coat (maybe over kill). Paint takes a while to cure, and you'll end up with a better result if you really take your time between coats. It will be a stronger layer and should (maybe) be more resilient to scratches. And it looks great.
Panting is not recommended, in my opinion. I tried it once, all that happened was my pants got caught on the rail of the receiver and pulled it off of my desk. Bad idea.
I love freedom and consequently America
