I have a couple gallons of "store catalyzed" lacquer, ML Campbell Magna Max I believe, that is about to "expire" (120 day shelf life after being catalyzed at the store). This is left over from my second foray into spraying lacquer and I WAY over purchased for this project.

What happens after it expres? Can it be "re-catalyzed"? Can it be used as is but perhaps is just not quite as durable? Or maybe it won't even harden after it expires?

This stuff was expensive so I hate to see it go to waste, any suggestions/thoughts?

Many thanks!
