Question About Rust on Mufflers.

[dragpack70]

Let's say you get a set of mufflers fresh out of the box that already have visible rust/oxidation on them. Let's say that they are the stainless steel 409 aluminized variety that are supposed to be resistant to rust-through, but they still don't look too hot when you get close.

 

Is there something that can be used to match the aluminized surface, but cover the rust and still resist the heat?

 

Or, if you decide to use some low-gloss hi-temp black on them, do you think that might promote more extensive rust under the paint?

 

Inquiring minds want to know.

I can't answer your question, but I can ask one in return. If you live in the Tx panhandle, why do you NEED mufflers?

 

I'm running straight pipes with the stock cats and it sounds awesome! just my 2 pennys worth.........

If the GT500 had a Harley-Davidson shield on the fender instead of a Cobra, you probably wouldn't. But, sometimes, the LEOs and safety sticker inspectors don't have anything else to do but look underneath.

Is the rust on the muffler body or is it only on the welds?

If you look at the pictures that have been posted of the kay are mufflers, you will see what looks like weld splatter that has burned through, or melted into the aluminum coating on the back of the muffler bodies around the tips. It may be the welding rod debris itself that is rusting, but it looks a bit unsightly anyway.

 

For example:

 

 

Edited to add:

To anyone who runs across this thread wondering about the rust-like stains on the back of the kay are mufflers: The stains are apparently welding flux or gas-off, and a little metal polish like Mothers will clean the discoloration right off!

 

Thanks to Slabo for the info.

My fear is ultimate body rust. Once it starts, it's like a cancer. I chased it for eleven years in my '65 Buick Wildcat and finally gave up.
