refinishing a muffler?
Posted by: GWLee ()
Date: October 28, 2017 11:50AM

I have a new exhaust for my car but not a muffler.

The muffler I have is great except for some minor surface rust. Has anyone ever painted a muffler?

I hate to replace a good part, but don't want the looks to take away from all my other hard work.

Is there a galvanized paint that is rated to handle the heat. I've seen ceramic paint and used it but not in a color that would match a muffler?

Thanks so much,

VHT silver! For headers.

Does it hold up well?

I ask because I used some on headers years ago, and it didn't seem to last long.

But paint technology has gotten better, I guess.


Thanks

Always worked on headers for me if I lightly blasted them first..

Lee read the can instructions too, some VHT paints need heat applied within a few hours of application.

I had a used 66 turbo muffler that I simply used powdered laundry detergent, water, and a brush to clean it. Looked nearly NOS when I was done.

Of course that won't remove rust. Might try it (if you have not already) to see if the muffler really has rust or just dirt.

My 66 had the mufflers painted black when I got it, I thought it worked well because it made them disappear instead of stand out. They had been like that for many years before I got it and ten years of me owning it and still looked good when I took them off.

Lee, I have used "Aluminum" colored paint on mufflers before.
Well, actually several times.
Look for "aluminum" as the color, not that super shiny Oakey Chrome in a can!
It has a look of fresh metal, without being overly shiny.
Since it is not right next to the exhaust ports(like headers are) it holds up extremely well.

Lee I have used 3 products that may help. The 4" tail pipe on my motor home is supposed to be stainless but it isn't. It started to rust so I cleaned it with Scotch Brite and alcohol. Then painted it with VTH silver, no pre heating. Its held up well for several years. Another product I used is Rustoleum zinc rich. This stuff is tough, Used it on my anchor chain and to touch up my galvanized boat trailer. Never tried it with high heat. The 3rd is LPS zinc-X this stuff is tough and supposed to stand up to heat.

Well thanks everyone. I seem to have several things I can try.

I cleaned the muffler with a scotch brite pad and it looks better and thought if I worked the one bad spot it would shine up. It only has one spot about the size of a grapefruit, that has surface rust. The rest is great. The pipe on each end has rust but nothing terrible, just looks bad.

Steve I seem to remember some of the paint's required heating after to harden it, I suppose. My son used some on his headers but he missed the final heat part and it flaked off. But I don't know how well he may have cleaned them before he tried to paint.

Mel I have one of the paint's you mentioned.

But I've made a few notes with the information you guys have given me. I will go look at some paint's and give it a go.

Thanks much.

The rustoleum changed the name to cold galvanizing compound a while back. It is great stuff, but not want you want for this as it temp limits. The rustoleum BBQ black is really good paint, that can take heat as in my wood stove, but its black Also, VHT now has a high temp primer. I haven't used this, but I may the next time I want to coat something where rust has started.

Not part of the OPs question, but since others are following this thread. Never ever glass bead anything you are planning on ceramic or VHT coating. The chances of flaking goes up a lot. Someone told me this and now I am a believer. Sand blasting is good, but not beads.

For best adhesion with any of the paints I would remove ALL traces of the rust either chemically or via blasting.

Hi-Temp Engine Paint has worked for me and doesn't require a heat cycle.

I agree with the Black.

Unlike Children. mufflers should be heard and NOT seen.

Just remembered I also used VHT silver on my log slitter and power washer mufflers. They were showing some surface rust a few years ago. Its holding up fine and they run probably hotter than a Vair muffler.
