What I got was Spray Max 2K Epoxy Primer #368 0032. One of the guys who works for me has an account at a local autobody paint place and picked them up for me at his discount. The can says that it lasts up to 4 days after activation. It has a plunger on the bottom of the can that breaks a membrane or something to mix the two components together. Says it needs to be used within 36 months of manufacture, so I've got 2 years left to use mine up.
I can't remember if Robert said he had thinned it for brushing, but his post on the garage journal forum are some good info.
