I bought mine from the local farm store, which is just a regional chain.. so I wouldn't have any idea what national chains might carry it.
You could send 'em an eMail with your zip code, and they could probably tell you who your closest retailer would be.
Somebody else here was interested in their paint, and told me they'd eMailed those folks and they were quite friendly and helpful.
Best paint in the world as far as i'm concerned. I put it on in November of last year, and not only did it sit out in the snow and sub 0 temperatures all winter, but I used the truck for all sorts of farm related work.. it was very resistant to scratching, and stopped a big rust hole in the passenger side running board dead in it's tracks.
I sold the truck to a guy, who sold it to another guy, who had it up on eBay recently.. it's in New Mexico now.. have a look at what the paintbrush applied paintjob looks like over a year later..
