I have a gallon of RM DP26 2K urethane primer surfacer and quart of activator that I bought for my project, what I thought was 3-4 year ago...turns out time has gone by faster than I thought, and this stuff was purchased in 2009!
I have opened the primer, and aside from the solids settling on the bottom, once I stirred it for awhile there are no clumps, and it looks good. The activator has never been opened.
So just how stupid am I to entertain using this? If I open the activator and it is not gelled and has no clumps, should I mix a small batch and spray a test panel to see if it is good? Would there be some obvious signs it is junk, and what would I look for?
I need to order more SPI epoxy and am not adverse to buying a new gallon of 2K if required, it's just a bit painful that this RM stuff was $400 for the gallon and activator when I bought it so if it Is reasonable to use it that would be great.
If this is a terrible idea, what the best way to dispose of it? Mix it up and let it harden then send to landfill?
