Old Thunder bird???????????

[Magnum in Ms]

Thunder Bird epoxy finish is supposed to have a shelf life of 2 years unopened .  I have some that has been opened and partly used that is about 2 years old. How do you know if it is still good?

I would examine it to see if it looks fine or different than remembered. Mix it up and either use or do a test to see if acts properly.

Worst case, you have to sand off and do over.

Thanks Jim.   I sprayed the gloss and it did fine but when I tried the satin I got some orange peel and wondered if it may be getting old.

The last bow I sprayed was with Tbird that was over two years old and it was fine. It was all satin.
