I bought this to fill in a couple gaps in the joints of a bookcase I was spray painting because it was recommended to me buy an employee from Home Depot. He told me it was sandable and instructed me on how to use a putty knife to get it into crevices and smooth it out. Honestly, I was pretty disappointed. The consistency of the stuff is like a gritty paste. It doesn't smooth out easily. I waited 24 hours for it to completely dry, and then I used sand paper to try and make it smooth adn blend in with the surrounding wood. The stuff was so gritty it wasn't possible to get it very smooth. Also, it started dissolving when I wiped down the piece with a damp cloth prior to painting.
