How do those of you who have mentioned Kroil remove all of the excess prior to casting?
Thanks

put in the minimal amount to begin with.
wipe with a q-tip while the mold is hot, then run a few boolits it'll smoke but don't cause any problems.
it seems to take about 3 go rounds with a mehanite mold for the kroil to really start to work.
you'll notice it working with the first use though and can tell when it's sinking in or wearing off.
i then add a bit more with the q-tip and waste a few pours and keep on going.
i have been doing a square lube grooved 429421 that refused to give up it's boolits but now on my 3rd application/heat cycle, it has gotten extremely/much more waay better and gets better with each use.
i have taken to just coating the mold with it after each use and leaving it on the entire mold, then wiping it down with a rag before starting and after warming.

Will Kroil work on aluminum Lee moulds too?

it does but not as well it don't seem to work into the pores like steel.
i usually lightly smoke the mold with a lighter for aluminum.
