Has anyone tried to paint a muffler (evolution .46) I was thinking of using automotive header paint I don’t think a rc engine gets any hotter than a cars exhaust manifold.

That would probably work, but why would you want to paint the muffler?

it might hold up to the heat but it may not be fuel proof

I saw a plane with the muffler painted black and liked the look

The muffler will run hotter and the heat may damage it?

Header paint should work and I suspect some of it is fuel proof, but like the others, I look at this and ask, Why? I guess a matching or blacked out muffler would look pretty cool, but I always come back to . . . . why?

Oh, Aluminum is one of the more difficult surfaces to get paint to stick to, especially oil soaked aluminum. Clean that puppy up really well before priming.

That paint will work great as long as you wash the muffler really well. Dish soap is the best, its made to get rid of grease. I don't think it will make the muffler too hot as long as you don't cake on the paint.

I agree that it would look pretty cool. If I were going to put in the effort, I would probably buy a new muffler and paint that. The odds of a successful paint job would go up, and if it didn't work, you could just go back to the old muffler.

Be sure and post pictures if you try it.

Good luck

I had a MACS tuned muffler on one of my planes.. It did look cool and also increased the engine RPM…

The black color was part of the production/anodizing process.. Go check them out...

They are not exactly tuned. They are called the Mac's One Piece Muffler. They are nice and light weight. they do better on some engines than others.
