1) professional jobs are out of the option and ridiculously high priced in my opinion!

2) I want to paint my bike, my friend just got an awesome air compressor, so I was planning on getting an HVLP SPRAY gun to paint it up

I'm trying to figure out what paint I should use? I'm pretty sure you use automotive paint, but the only brand I find online is House of Kolor, which using would defeat the purpose of DIY because it's so expensive. I basically want to paint the bike a cream color and the lugs orange (I'm going to paint the lugs not by hand). What type of paints exist? and Where do you buy them? And do you use spray can primer or prime via the gun? How much do these paints cost and how much do you need to do a frame/fork?

Thanks!
