Blowing it dry with a blow gun, allowing it to air dry for an extended period, etc doesn't make it safe. Remember, cast aluminum is like a sponge.

On a related note, using brakleen anywhere in a shop where there is an open flame (wood stove, kerosene space heater, etc.) is the same situation. I made that mistake many years ago, once. Bad stuff.


If the results don't match the theory, change the theory.
