Aviation Paint

Where can I buy aviation paint local to north of Seattle? I was hoping to not have to pay shipping. But am giving up on that. I want Sherwin Williams JetGlo but even SkyGeek is out of some products. Auto supply stores have PPG but it is their car paint. Same with DuPont.

Is there a store in Everett, Arlington, or Bellingham that can supply aviation coatings of any of the major manufactures?

Thanks

What is the difference?
I painted replacement ailerons with color matched catalyzed acrylic enamel that the local PPG franchised paint store sold me.
I did it myself and am totally satisfied. I was warned away from modern automotive paints, with special colors and metallics etc. (too expensive, not what you want on an airplane...)
Inquiring minds want to know...
