In your opinion is it better to paint the fuel tank brackets with powder coating or with an epoxy primer + paint for high temperatures?

I would like to prevent the rust from returning.

Thanks,

I think powder coating is better because it is baked on (400F) and all the moisture and oils are burned off the surface, Then paint it any color you want! I use engine paint because it is good to 500F,

I don't get that. It sounds like regular paint on top of powder coating. Am I missing something?

DHS928

Yes, Base coat baked on and top coat that can be any color you want, around here the cheapest powder coating is usually black because they do it in batches. Then I paint it the color I need. Have done that on my warbird and car parts for twenty years, it holds up well.

Are you talking about the tank straps/cradle? Why would you need high temp paint unless your exhaust shield is missing in which case the plastic tank is at risk.

Agreed about the resistance to high heat that's needed. That area should be reasonable, from a temperature perspective.

I think, if you have the chance, that powder coating is a nice way to ensure that you really seal the metal surface. And, since it's plastic, it can move and flex and take a little bit of abuse (rocks, gravel, other stuff that can get kicked up under a car). On top of all that, you can find most any color you want directly via the powder that you choose. As an example (no affiliation, there are other great suppliers), check out prismaticpowders.com. They have all the colors you'd ever want and you wouldn't have to paint over things.

Thanks for your suggestions.

I proposed high temperature paints only because in spray can it costs little more than normal paints and I think it is more performing

I've had pretty poor luck with long term performance of most single part paints. If you can manage to get the powder coat done, I would go that way for sure. If you have to go with paint, consider a two part paint. In the US we have Awlgrip and Interlux Perfection, which both last a long time.

Well if they are rusted, you have to deal with the rusting issue which means stripping then galvanized coating... I think black oxide would be best for such applications.
