why buy basecoat ready to spray? just buy base and reducer. Why do you need colored primer?

I get all my paint for autocolor. They have about 10 store around atlanta. Not sure of any in gwinnett but here's the website. http://www.autocolor.com/weekly-specials.html

Why are you only interested in Sherwill Williams and Dupont?

I use ppg, omni, pro-spray, house of kolors and have never had a problem with them.
