Throttle Body Paint - What's good

[larrycavan]

I'm getting ready to paint my throttle bodies, fuel tubes, etc. Going with Gold bodies with Gloss Black Fuel Tube and other trim items in black.

I want something that will hold up to heat and fuel. Short of powder coating....got any paint brand suggestions?

What material ?. If aluminum, then you need to sand all parts CLEAN from oxidation and degrease with acetone.
As a base coat you need to use 2K (acid hardening) which is suitable for zinc plated on aluminum surfaces.
After that any 2K automotive paint+clear coat will do. Bare metal surfaces must be sprayed within 30min after degreasing with acetone.
Any longer and oxidation will start to build up and you are not going to get proper adhesion.
