Where to buy paint?

It's been a while, but I sprayed a lot of vehicle with the S-W paints when I was in the business. It was as good as anything else I've used, and the price is quite competitive.
There are 2 things you really have to be aware of when buying any paint.

First, if the color is any share of red/orange or blue, expect to pay big bucks for those colors.

Second, the cheaper lines of paint in any given brand name will not give the coverage that you get with the more expensive lines in the same brand name.

Soooo,,,,,, it's sometimes false economy to buy the cheaper lines because you end up using more than you would with the more costly lines. A case in point, a lot of reds and oranges have VERY poor coverage, even in the top line paints. You are usually better off to buy locally, and then if there's a screw up you can at least get some support, or another quart of paint when you run out 1 gun full before you have complete coverage.
