Hi, I'm wanting to paint my aircooler, more importantly, the twin carbs, manifolds, alternator etc... will i have to use any special kind of paint so it will last?
I guess I'll have to well clean them, then give them a once over with etch primer, then something that will take the heat?
I'd quite like to get this sort of effect:
can anyone advise the best way?

yeah that looks nice, I like the subtle approach with the the satin finish..
you want a high temp engine enamel, clean, decrease, repeat... I like using dawn for a third wash rinse with scotchbrite..

Have your engine tins powder coated. They will look more professional and last much longer than just paint.

I was more worried about the alternator, manifold and carbs... would they powdercoat too?

They would just have to be heated to melt the powder coat. No more than what they usually see while running. Aluminum and probably magnesium, need a special primer for the powdercoat to adhere to properly. The only issue might be preparing the surface's of the carb and alternator for the powdercoat. That's usually done in a glass peening machine, like sand blasting but finer. You'd have to ensure no media gets into those, or take them apart and just powdercoat the bodies of them.

Powder paint is the way to go. Carbs and alternator will need to have the internals stripped.

I'm having my manifolds ceramic coated. There is a satin black in for it as well:
