I am giving away four full 50 gallon barrels of Part B resin spray foam insulation and three barrels that are mostly empty. These have expiration dates of 2020 and 2021. They came with some other things I purchased and I have no use for any of it. I also have a heavy duty drum dolly that is spring loaded. Must take all (barrels and dolly) as I need it out of my way. Can pick up in Murray, KY. Please call or text 270-752-0524 if interested. No holds...first one here with a trailer takes it home (full ones weigh 500 pounds each). Can send pics of drums, drum labels, and dolly. Thought this might be useful to someone.
