Muffler looks like s--t - paint?

toddu · 10-16-2008, 06:47 AM

Is it possible to paint the muffler? I painted some other parts (engine tins) engine paint, which I think was good to 500 degrees. Does the muffler get hotter than that?

I was thinking of wire brushing it, and then just painting it that grey primer color I believe it was originally (stock muffler - 911SC).

I would take it to a reputable powder coater and have them apply a black ceramic coating on it - worked for me and keeps temps down, significantly. The key is the prep work before paint and they can blast it before they coat it.

I can't tell ya how many times I have painted the muffler only to have it look like crap after a few months. Get it coated like stated above.

I was trying to go the low $$$$ method because I'm planning a rebuild probably in the next 2 yrs and the muffler will go away. So, would rather not go through the hassle of taking it off, paying to have it blasted and then coated. Not worth it to me.

I painted mine with that high temp silver BBQ paint (I think it's resistant up to 1500*F), and it looks as good as the day I painted it 10 months, 5,000 miles ago. I wire brushed the whole thing, then thoroughly cleaned it with solvent, then painted it.

I couldn't be happier with the results

BBQ paint, yes, I've used flat black Rust-oleum with good results.

Never thought about BBQ paint!!! Thanks for the tip.

I have had good results painting Heat exchangers and Mufflers with "Cold Galvanize" , which is a rattle can product consisting of pure zinc granules in a binder of some sort.
Farmers ranchers use it a lot for metallic objects that live outdoors all the time.

VHT Silver. perfect long-lasting results. Search for it online.

I too have had good log lasting luck painting an ugly muffler. It lasted a long time for me then I got an MK!

n.b. -- prep is the KEY

I'd try that brush on stuff that Eastwood sells too.

I use eastwood cast iron grey manifold paint on mine.....it only costs $16 for more than enough to do several mufflers or lots of touchups....I am in the process of getting a new M&K Muffler and it will be painted before the final install using this paint.

I used Wuerth hi-temp paint in a rattle-can and it worked great and is still on the muffler!

+1 for VHT High Temp paint.

Rattle Can, easy to use, lasts, great.

is the correct VHT color grey or silver?

VHT people did you use the primer first? my muffler has a good black coating on it now but after doing thesport muffler conversion i need to repaing parts.

I hear a lot about the VHT lately and it looks great from what I've seen.

I did mine prior to the VHT phase and I used the POR20 manifold grey. They still look like the day I painted them years ago. Very happy.

Randy's message suggesting prep is the key was too brief.

I'll repeat. The preparation of the base material is probably more important than the choice of paint coating.

My original muffler is going on thirty some odd years old and it's still fine. About 18 years ago, I had the outer skin sand blasted, then powder coated. It's still intact. However, the insides are slowly disintegrating into a sport muffler. The inside can't be coated once used.

Most of the mufflers shown above look like they are new, or have gone through the ringer in terms of prep. If you do not spend a lot time on prep, I don't care what paint you put on it, it will look like crap after a while. I still have the org. muffler from my 72 and I spent hours trying to get all the old rust and crap off of it and no matter what paint I used, BBQ paint, zinc, VHT, whatever, it still looked like crap after a few months.
