Oh, and one other thing... (I just read the initial post again). A lot of folks think they are going to save a bunch of money painting their bike themselves; in reality this is not gonna happen.
If you don't have any of the stuff to paint you can figure on spending about $450 retail on materials -- that's if you already have the compressor, gun, buffer, respirator, sanding blocks and other stuff which could run another $1000 without even trying.
Okay, so if you are a beginner you can plan on spending about 4 times as much time as a pro painting your bike, so let's say 60-80 hours. How much is your time worth?
I say if you are doing it as a hobbyist partly for the fun and education, go for it. If you are just trying to save money, you might be surprised how much you will spend in the end.
