My single walled SS tips have never discolored, and have been through hell with the stones/tar/salt that they have seen, and still shine perfectly.

 

It's also about the quality of the SS in question. T-304, T-403...etc
You can get the bargain tips that'l last one season, or High quality tips, from Mag,Borla,Roush and so on that will stand up to being abused under a truck.

I've had tips last years with my trucks, and use them all year round. Mind you a bit of maintenance is required in the spring.

 

Nerv Dull is da bomb!

 

hey thanks yall i got it out with a type of scotch brite pad used for cleaning stainless steel pots and pans, worked well on the tips.

 

Not entirely true. Certain grades of stainless, the ones with the right concentration of chromium, nickel and molybdenum added into the base steel alloy are completely rust proof. The chromium/nickel/molybdenum mix creates a microscopic boundary layer that stops corrosion dead in its tracks on a molecular level. The rustproof stainless is known as grade 316 and 316L, the 304 that most exhaust manufactures use is not rust proof just resistant. 304 is also known as 18/8 stainless, meaning that the alloy has 18 percent chromium and 8 percent nickel content. Better grades of stainless have higer nickel content such as 18/10 (food grade) and 18/12 (medical grade) and the cheaper 409 grade is known as 11/0 and has no nickel content and can be worked as mild steel, can be magnetized and its primary use is automotive exhaust systems.

 

On a related note, How do you polish Black chrome stainless tips? When I first had them installed I polished them a few weeks later and the polish took the "black" right out of the tip. I had it replaced with a new one under warranty and the place said they have never had that happen before. The polish said it was safe for stainless so I was just wondering. I am trading it off for a 09 in a couple weeks once it gets built but I might have them installed again on my 09.

 

I hear ya!

Not popular on this board i guess....but haven't tried anything else that performs quite like it.

 

can't beat never dull. Will make them look brand new!!

 

I've never tried it on this type of discoloration however. So not sure how it would work on it,

 

Never dull works good. But you need to go over it with 000 or 0000 afterwards. I did mine 2 days ago.

1.Put Nevr Dull on (don't wipe it off!!)
2. Scrub with 000 or 0000 ( I used 000 first, then 0000 after to clean up)
3. Wipe clean
4. Use Blueman Metal Polish afterwards to leave a nice coat of wax on it so it wont happen again.

It helps to use Blueman periodically.

 

that yellow brown color is due to heat when steel is heated it will go through a process called tempering it starts out yellow then goes brown then as more heat is applied it will turn into blues and purples adventually turn back to matte gray. its the steel hardening makes it more brittle and adventually makes it rust

 

Never needed anything but N-D, I assume you mean following the extra steps for heat discoloration.

 

Yes I did.
Sorry for the confusion.

 

Polish with Mother's Mag Polish. No need to scratch pad. The tip on my '07 did the same thing every time I pulled the boat to the lake.

 

nice! yeah i tow my boat a ton thats prob why its so bad.
