I saw these 2k (two part) aerosol can's while at the jobbers last week. They are made by a company called SprayMax and come in a Epoxy Primer, Primer Filler, and a Clear Coat. This among other things they make. The components are separated in the can. When your ready to use it you push a button into a part of the can to release the catalyst into the material. Then shake as usual.
I can't find the company who makes it, just vendors. I talked to Len about it and the immediate downside we could see was the pot life. Like any other 2 part product once you mixed it you have only so long to use it.
I passed on it this time for that reason, I didn't want to waste half a can at $15.00~$20.00 a pop. I like the concept though. I'm going to try and contact the manufactuer so I can get some more specifics. Weight of Solids per Volume RTS and coverage specifically.
