I agree with Dick M.

Steam cylinder oil and graphite boils off the volatiles and leaves a durable coating.

The oil in the Neverseize will boil off if you get it hot enough.

True enough but is around 900 Degrees before that begins to happen which is generally not attained in models.

Is really not a good choice for this application

Should be the same for steam oil.

Even if the oil does boil off it seems likely in either case you'll get a finish you don't want to touch.

You might want to start off with painting the smokebox with a stove pipe or high heat paint, then over time apply graphite and linseed oil over it as it needs it.

How does the graphite and linseed oil hold up to cleaning? (general wiping, mild detergent, etc.)

I have to chuckle. What about the first four answers to the question?

Asked the same question. Recommendation from Gregg Glos of MSLS (who has built more engines than anyone I know) was to use this. Looked it up on YouTube and ordered two cans. Says to cure it at 400 degrees minimum.

Rated for 1200 degrees

These people claim to stock Cast Blast 1200F:

I maintain a "boiler" (actually a water heater) that needs this, and I can see other possible applications. Surprisingly inexpensive. How well does it hold up to mechanical abuse?
