Re: Lee Six-cavity molds.
I have been casting since the early sixties (yes, I am that old). I have used smoking with a match, butane lighter, candle, etc., Frankford Drop Out (over spray plugs up vent lines), and Kroil (in a can, not an aerosol spray).
The Kroil works fairly well, but needs reapplying too frequently.
I have read all the stickies (many are years old), but want to know if there is something that is currently state-of-the-art that is better. So, what works better (if anything), and where can I get it?
