Update:

Got this gun... http://www.tool-sale.com/full-size-hvlp-spray-with-metal-regulator-p-71.html

I think it should work alright. I am going to test it on a fender I have..

Got the Pressure switch, and installed it... My compressor finally turns off! haha

I'm going to head over to home depot soon and pick up some Satin- Anyone recommend a respirator I should use? I was looking at some 3m ones- dont know which to choose... Im probably going to pick up a half-face mask one...

Have new front and rear bumpers... I was wondering if it would be wise to paint certain panels seperatley... such as the bumpers, fenders, trunk and hood...?

I will be putting up some before pictures soon...
Started preping the trunk with 500 grit paper... it's nice and smooth =)
