    Default resin life

    I have access to a free 55 gal, never opened drum of polyester resin.The only issue is,is that it is about 8-10 yrs old.Is it still usable?

    Thump on the side of the drum, if it sounds like it's full of concrete at the top, its junk (it crystallizes), if it sounds like it has pudding in it, the resin may still be usable...Typical shelf life is two-three years, but I have seen much older being used and never had a problem..

    I would get a piece of cloth or mat and make a test on cardboard to make sure it cures properly and is plenty strong, I wouldn't think it would be a huge problem, but would not build a boat with it...may be OK for repairs and such...

    There's a reason it's free...the same reason garage sales exist...the bigger idiot theory. 400lb drums full of worthless goo are tough to get rid of...which is probably why it's free. If you're doing a big job that requires that much resin...it'll be tough to redo if the resin doesn't perform correctly, so I wouldn't take the chance. If you're just doing some repair work, what do you plan on doing with the other 54 1/2 gallons?

    Default Resin

    I would'nt even consider it.Take posession and you take responisibility and with you living in Calif. if it is no good it has to desposed of as hazardous material and I know when I moved into my new shop I had to dispose of small quanties of hazardous materials and it was very expensive.

    I do not live in Cali any longer this is in Texas.I still have a personal problem taking possesion of it if it is no good.The drum is still liquid and has never been opened.The person who originally purchased it was going to make kit car bodies and never did.I have made a few plugs/molds for scoop's and was considering using it.I think GT has a good idea.I'll mix up a batch and see if it goes off.Thanks for the reply's.
