 Ask them if they want it first. But if it has to go away, where is away? If it has to go away, pop the lids, stir it up the best you can, and then put it outside in a safe spot where nobody's going to get into it or animals won't get into it or something, and just let it harden up. In the summer heat, this will only take a few days for latex. I put out two gallons last Wednesday.
