I love this stuff. Have been using it for years for random repairs around the house. Things have held up in some cases for years! Once opened, I like to take the black and red plastic caps that are under the spreader, and keep them in after squeezing all the air out to help keep any oxidation to a minimum. I've used it for plastics, metal to plastic, car parts, vacuum parts, holding up undermount sinks, countless repairs that have saved me tons of money.
