here in Alaska, Carquest carries PPG products, and NAPA has their own line with Martin Senour paints. I've used the NAPA/M-S epoxy primer with good results.
You might check with your local Carquest or NAPA stores about paint. O'Reilly can also get PPG products, but they will probably will have to order it in. I suppose Carquest and NAPA may have to do the same.
