They used to make a 4 oz. liquid version in a squeeze bottle , which I also like and apply the liquid dry lube with a Q-Tip to the cavities when I need a mould release . It only takes a few seconds to dry I'm sure any Dry Lube that's Teflon based would work ...
The good part is it doesn't contaminate the cavities and it doesn't need to be removed .
Works great on top and underside of Sprue plate and on top of blocks ...lead doesn't stick to teflon coated metal .
Really amazing stuff to use when casting ...spray pot sides , casting ladle ...any place you don't want lead to stick to .
