Tony, what surface preparation did you make on the boiler prior to the finish coat i.e. any etching or primer?

I originally sprayed it with etch primer but I was concerned that it wouldn’t take the heat so I removed it and sprayed the barbecue paint directly on the boiler.

Thanks Tony, didn't know you could get high-heat paint in anything but flat.  Will have to browse amazon...

I have had very good results with this paint, a ceramic engine paint, up to 500F, no oven bake required to cure, goes on thin and dries quickly. Seems to take abrasion/handling quite well too, I have been using it on my steam engines and also RC boats. It comes it a bunch of colors, including semigloss black. Lots of auto parts stores carry it.

Thanks too, crueby, engine paint I've heard of, but bbq paint implies temps up over 500F.  Rustoleum Hi-Heat paint for instance, goes to 2000F.  And comes in gloss/clearcoat versions, which is news to me.  The high heat stuff does require a high temp. cure (600F).

Thats he nice thing about the engine paint, if you dont need use above 500F anyway, it cures are room temperature, and I have found it goes on in a thinner film that is more durable. If you need the higher heat range, then the other types are needed.
