Painting the muffler
No, I'm not being anal Most of my exhaust system is exposed on my speedster, and I want it to look good. I have tried using silver Duplicolor high-temp spray paint (made for engines), but it always starts flaking after a couple of weeks. I think the problem is that there is a thin film of rust on the surface that prevents the paint from sticking well, but regular Rustoleum paint says it is good only to 200 degrees. Any suggestions?

Re: Painting the muffler
Rustoleum barbeque paint (the brush-on kind in a can) worked great for me.

Re: Painting the muffler
I'm reading on the the Duplicolor site that there appears to be several engine hi temp paints.
Duplicolors VHT Flame proof coatings are supposed to good up to 2000 degrees. They come in Aluminum, silver, and cast. The engine enamel is good for 550 degrees. They also have a High temp paint that is good for 1200 degrees. Which are you using?

Re: Painting the muffler
There is your problem. No matter what type of paint you use, it will not adhere properly if the surface isn't clean. You need to bust out the grinder with a roloc disc and grind it to bare metal, clean it and shoot it with hi-temp.

Re: Painting the muffler
I'm surprised the powder coat has held up on the manifold, it gets pretty hot.

Re: Painting the muffler
I used flat black high temp stove paint from Tremclad. Brushed it on a clean muffler and exhaust manifold several years ago. Still looks fine.

Re: Painting the muffler
I have been told that if you temper the paints it will last longer. That is running a few hot/cool heat cycles prior to getting out on the open road for a day.

Re: Painting the muffler
I have always sandblasted the exhaust parts, either new or coated in heavy rust, before painting them. Never have had a problem with high-temp paint not sticking.

Re: Painting the muffler
How about one of the stainless steel mufflers sold by most suppliers?

Re: Painting the muffler
That's the ideal solution if you have a spare $300.
