Please don’t mention model airplanes. I wake up screaming because I have nightmares about those things. Although…. This is interesting.A search here should turn up some ideas. I do remember that nitromethane-resistant model airplane paint is an option.
Thanks for posting that. I should ask one the local paint gurus if they can mix custom colours of a paint similar to VHT. Then I could get some of the light bronze/gold coloured stuff.I've used VHT Caliper Paint, Cast Aluminum (SP735) with good results. You bake it after application to improve resistance. Gasoline from tickling the carbs doesn't damage it, and the residue comes off safely with WD40.

I have a bunch of photos showing carbs (some NOS) that were painted with what I would refer to as a light bronze and some that are fairly dark. These are all Amal TT carbs that I’m referring to. I did a fair amount of digging on the subject and somewhere amongst the pile, there is a copy of an Amal TT carb brochure that mentions the coating, but doesn’t give any detail IIRC. I’ll try and dig that out if you wish.I think the VHT, though satin, is glossier than the original Amal paint. But should it have a bronze tint? I've seen that on carbs, but assumed it was an artifact of aging and gasoline exposure on 70-year-old silver paint.
Anyone have an original-paint Amal component that's been away from light since 1949, to check the paint finish?
Definitely paint… at least on the ones I’m referring to.So painted and not cad plated then ?
