Default Airbox paint

Which paint do you recommend for painting the FAB (filtered airbox)?

I'm considering using Rustoleum Engine paint since it claims to be gasoline resistant.

Any comments will be much appreciated.

I use the same PPG single stage urethane paint I use for the cabin interior, panel, engine baffles and such.

Does it need to be painted?

What Carl said. Nothing from a spray can is a tough as two-part auto paints.

I used West Systems epoxy pigmented black. Warm the airbox with a heat gun as you brush on the epoxy to help is flow out.

That is a good idea! Thx
Still wondering if it needs a finish or if that's cosmetic.
My Frankensnorkel is still "Commando". I kinda like it.

Default No requirement

There's no requirement to finish the exterior of the airbox. I didn't! I don't think any of the Van's demos have a finished/ painted airbox.

My RV-6's airbox is unpainted. It is no prettier or uglier than when I completed it 22 years ago.

It'll see limited UV exposure, so no need to protect it for that. Limited water exposure too, except maybe on the interior, and in any case fiberglass can handle that short-term moisture.

I'd say that any paint is purely cosmetic.

Perhaps, but I seal all cowl and FWF fiberglass to protect agains oil and such. And yes it is cosmetic, just like painting your plane.

Take the little bit of time to paint this along with baffles and such. You will have a much more “finished” look.
