Shelf life for urethane paints

4256 Views 1 Reply 2 Participants Last post by  dana44
Anyone know what the shelf life is for urethan base paint?
What about urethane clear coat? I have some clear coat that is several years old - not sure if it is any good - still liquid.
Is the hardner same shelf life?
What about a high solids primer? or epoxy primer?

I don't know what the real answer is, but I know I have used 10 and even 15 year old stuff, possibly even freezing during that time, and as long as it was mixed well and strained, not a problem, from paints to the primers. I cannot give this answer for clear coat, I have always used all of it when I bought it.
