Paint for Engine Baffles
 
I've decided to paint the aluminum pieces of the engine baffles. I have some PPG single stage urethane left over from interior that would be the right color.

Has anyone painted their baffles with "automotive paint" with success? Or, do I need to use a high temp paint?

Baffles paint
 
I used automotive base/clear and no issues after 7 years.

I use PPG single stage urethane for the interior and all firewall forward aluminum, including baffles. The oldest project is now pushing 20, and it still looks like new.

I use PPG DP-40LF as the primer under the urethane.

Thank you Paul and Carl! Just the answer (and experience) I was hoping for!

I used PPG Concept on my RV-10 baffles. Going on 9 years and they have held up very well.

Once mine were all fitted, I took them all and had them powder coated. That stuff is tough. No regrets.

It was a mistake to powder-coat the baffles on my C180. Over time, the paint flaked off. And the baffles got dirt embedded in them that I've been unable to remove.

I won't make that mistake on my RV-3B.

What's your plan?

23-years ago, I painted my baffles with a rattle can of paint. Except for chips and bugs, it has held up ok. High temperature paint is not needed.

I'm not sure I actually have one yet. Probably one of these -

Two-part spray paint
or
Polish
or
Anodize.

I'm leaning towards polishing them.
