I heard about the propane here & tried it. It works great with
Rustoleum & not at all with Benjamin Moore. The B-M will be skinned
over in 3 days, even with the propane. I also tried CO2, with similar
results. Fortunately I don't use much oil/alkyd paints nowadays.

That's extremely strange. Did you ask BM about it?
