12-Sept-2011 Not everything goes to plan. I had primered and painted the smokebox with high-temperature paint over a year ago. Noticing some flaking at the rim where the rubber mallet had struck it (to drive the smokebox onto the boiler), I discovered I could flake the paint with my fingernail. There seemed to be no adhesion of the paint to the metal, running a scraper over the shell ploughed the paint off with not effort. Instead of just touching up the paint, I scraped the whole shell, sanded, cleaned prepared it for fresh paint. Looking at the instructions on the Rust-Oleum very high 2000 degree heat paint, after painting I was supposed to bake the part in a 200 degree oven for 20 minutes, then 300 degrees for 20 mins and then 400 for 20 mins. I never did that and now that it is 'one with the boiler' I can't properly cure paint. I suspect failing to do so caused the flaking problem. i will use 500 degree paint instead, which does not require baking.
