Vapour blasting paint or not paint

I wonder if running the engine for a short time will cure the paint food for thought,

It sounds like a lot of hassle but I don’t really mind taking the engine out again if that’s what it needs.

It may cure the head and barrels after a while but it won't cure the crank cases as they don't get hot enough.

I've left the head on my main rider 500 unpainted for 20 years and never had any oxidation and it cleans up fine and no worries of flaky paint. But always painted the cases.

Spray can paint unless it's a 2k mix never fully cures! It dries via evaporation of the solvent . Putting the Cases in the oven to "cure" is a waste of time and energy. It does not make the paint any more durable or chemically resistant. If you want a paint that will withstand time and chemically resistant use an Epoxy or a 2 part paint with a catalyzed property
 These paints cure via chemical reaction and are durable for the long haul.

Through lots of personal experience, I would dispute most of what you have said. The Simoniz engine enamel (SIMVHT31D) is very hard wearing, retains it colour and finish well, it's easy to keep clean. It is highly fuel and chemical resistant but, if you have a continual fuel leak on it, fix the leak before it damages the paint. Follow the instructions on the can and it's perfect.
