Rusted muffler paint options...

Hey guys,

I have 1 major just stripe on my right muffler, right on top.
Looking for options...
I tried cleaning it up and using a bit of high heat aluminum paint to cover, but a week or 2 later, rust comes through....

Found a Duplicolor Chrome paint, but it's not high heat, but they do have a Hight heat aluminum, or VHT have a nice looking flat silver that would give a unique look.

What would be the best thing to use as an anti-rust primer before the high heat? Or would a good cleaning with something like navyjelly work?

 

Sorry bout that ghost

Ima tag on to this thread and ask what to do about completely rusted pipes? From the header to the muffler is just rust. If I try to sand it, will it go through? I don't want shiny pipes though - black pipes would be ideal.

 

My original pipes for my parts bike were rusted horribly.. I chucked a wire bit into my drill and used it to get all of the rust off. Then I used some flat black high heat paint (I'll have to find the paint can... picked it up at local auto store - good to like 1000 degrees or something). I put on 2 coats 30 minutes apart, on three separate days. (so 6 coats of the rattle can).

I still have the pipes in my garage after 14 months and no rust seems to have come through. That paint really hid a world of sin. I know I have the can still in the garage somewhere - I will find it. If I can, in the next day or so (can't tonight) I will try to take some pics of my pipes.. I think i have some 'before' pics somewhere too.

 

Sweet, thanks a lot jgb! Sorry if I hijacked your thread Ghost, I'm sure someone will come answer you soon though!

 

actually once I can find my pics and that paint info, it's for both of you. I remember that this paint had a few colors - including a matte silver.

 

Neat. Can't wait lol. You remember how much it costs?

 

That duplicolor chrome stuff sucks. Its "shiny" But no mirror effect. You cant clear coar it either. Turns it grey.

 

If you are just painting flat black you might try BBQ paint.....

 

there are also different colored high heat wood stove paints

 

Psudo no problem ... if you like a flat black, try the Duplicolor high-heat ceramic... has a nice look and texture...

jgb, thanks for the info... goo scouring.. maybe a cheap can of BBQ paint will work as a primer then go for the matt silver....

 

There's high heat, and then there's flame proof paints. You need flame proof.

 

Sorry all, I didn't forget - work busting my tail. hoping to get pics tomorrow, no lights in my garage so can't do at night

 

So I have a few questions: is the BBQ paint like dry looking black? Also, when I go to sand off all the rust, what grit sand paper should I use? I've never sanded anything without the sand paper already supplied and I don't own one of those neat spinning brush deals...

 

I'd start with some 120 or 150 pretty lightly, then move to 220 and 400 if you think you need it. Its mostly start light and as the rust comes off and move up until the lines from the previous grit are gone. At least thats how I do it. You can also try soaking in an acid bath overnight or electrolysis. Electrolysis is a lot easier than it sounds, but not for use with anything you want to keep chrome on. Benefit of electrolysis is it does not take any metal off like sanding does, just removes rush. I'm actually planning to acid soak mine this week and possibly some electrolysis...

 

If you need to patch a muffler, you only need to clean off the rust and apply a couple layers of fiberglas on them. Fiberglas gets hard the hotter it gets, so it works [erfect for patching any kind of exhaust system. ANd you can paint over it with BBQ paint to cover up the patch.
I had an old 550 Honda with rusted out mufflers and I use fiberglas to cover the holes in them. Then I painted the mufflers with flat black BBQ paint and it lasted for years. It didn't look too bad either.
