Nope. It took me about three-four hours to put 4-5 coats on all four wheels. Here's an old post of mine
The reason for brushing is that it takes forever to tape everything off. I used a Big Gulp cup with a paper towel over the lid to minimize over-spray(as I filled it up) for my paint cup. Worked great.
To clean the calipers I used a wire-brush drill-bit from Ace Hardware, and my cordless drill. It took about 10min per wheel. Make sure everythings nice and shiny before you start painting.
Another trick that I found is to use a sponge-brush to paint with. The sponge brush won't leave those "lines" that you get after painting with a regular brush. Also it's a good idea to have a couple extra paint brushes around...
One more suggestion: Jack the car up so that you can do two wheels at a time, that way when you're done with one side, the other will be dry and ready for another coat. Back and forth. I did 4 or 5 coats with Duplicolor 1200 degree paint ($4.95)and the calipers look almost rubberized.
