Re: Shelf Life of Automotive Paint
I have been told that the actual urethane single stage paint will last a long time - years even if opened. The catalyst, however once opened, does have a much shorter shelf life. The paint companies say a few months at most, however they are in the business of selling paint. I have gone a year with a opened can of catalyst and it worked well. I keep the paint in a cool basement (60 degrees usually). Someone said if the catalyst is clear looking it is probably OK to use, but if it is cloudy, don't use it.
Hope this helps.
