I fill a little 8OZ jar w/ a lid to dip castings in. It lasts forever like that and you don't have to mess w/ the big bottle every time. I also use a paintbrush to apply it and have had good results that way too. I set it on a cardboard from a blister pak to let excess drain and cover it w/ a clear plastic cup to let it dry. It comes out shiny w/o having to buff it or anything.I love the way this stuff makes these shine, do you let it drip dry sand or have to buff it in any way? thanks for the info!!
