I use map gas and go forever....sometimes the original OMC paint doesn't even show much harm amazing stuff.

Acetylene, map gas I've used them all. Map gas or an induction here is all you need that in a few crayons.

I think that the ally conducts heat away so fast that it can soak up a far bit of heat ,and I think you gain more by heating moderately and cooling a few times than you do by over heating it once
I looked at using crayons but I could never find ones the right colour.

Yeah colored crayons discolor the paint for sure, I just use light or dark depending on the motor so white on white and the darker on the darker.
