Re-painting new Bursch exhaust

chrisreale · 10-08-2002, 09:54 PM

I want to treat this muffler with a anti-rust, high temp paint. Should I just sand it down and repaint it, or should I treat it with a special primer?

In an earlier post I asked the same question with respect to high-temp engine paint used on cooling tin. The consensus seemed to be to clean the metal and shoot it directly, without primer. Or follow the mfg's instructions. Not comforting, since I used engine paint without primer on my tin and it has not held up very well.

What paint are you planning to use?

Hey Chris,

I know I was peddling my "rustoleum BBQ paint" I used last week, but POR 15 has a Hi-Temp paint that I bet would be very good protection.

Check it out,

I have the rustoleum bbq paint, and was planning on using that. I will look into the por 15 as well. Is Por-15 only on-line sales, or do they sell in stores as well?

Well, as far as I know Pelican doesn't sell it. I've always gotten it online. With POR-15 you don't have to primer it, in fact you should either rough up the surface or strip the paint off completely so it bonds correctly. Since you've got a brand new muffler you might want to consider spending a few extra bucks on POR 15.

Anyway because my muffler was already installed and pretty old I just used the BBQ stuff. It really does work well. Not sure on primer, I sure didn't use any. I think that stuff was designed to go right onto metal without it. You'd need hi-temp primer of course.

Good Luck,

There is also hi-temp powder coating material that can be used on exhaust.

Sorry I don't know the name of it. I only know it existst because I was witness to money-no-object modifications to a P-kitcar.

You get what you pay for....
Don't waste your time and $ on the BBQ paint of any brand, they will blister easily, I have seen this from a friends car.

He finally used POR 20 "manifold gray" and no blistering\peeling after 2 yrs. so far. They are @ $35 a pint, enough for probably 4 mufflers.

You will need to call\email them to see who carries them locally
in your town.

Check out his "details" page, looks awsome to say the least.

We have the Wurth High Heat Paint that works well.

I used the por-20 black, it worked great. A word of warning, clean the metal well and try your best not to touch it after you prep it. I sand plasted mine and made the mistake of grabbing it and carrying it over to the area that I paint in. Oops, the area I grabbed peeled. I redid that area and it has lasted two years so far. If and when I do it again I will clean everything with prep-sol before I paint it. Here is a picture of mine. As you can see the muffler itself is stainless, if you look closely at the collector you can see some peeling, that's were I touched it. It's been fixed. I always buy online

The co. I work for sells H/T paint for Snowmobiles, ATV's, PWC, and Motorcycles. The best prep is to have the parts to be painted sand blasted. This gives you a great profile for adhesion!
