this is related to my other thread, but I figured I would get quicker results here.

I want to order some epoxy primer- but I dont have a paint gun or compressor-

can this be applied any other way besides through a gun?

I have seen it for sale in an aerosol can, but how does that work? Is this type of primer a two part system with a catalist?

If so, then wouldn't that mean that an aerosol primer only have a certain amount of time to be handled until it cures? Or is not how epoxy primer works?
