So this is my weapon of choice for wood filler, that will not show. MY whole life, I use a little and by next time its dried out to the point I just throw it away and buy new. There's tiny little print on the can saying if it dries out, just add a little acetone to the can and voila, good as new, I tried it, and it worked fine My other perplexing question regarding this product....... Why do they print the cans upside down?
