About a year ago I purchased a ss exhaust tip for my vehicle, it aged quickly, turning brownish yellow 'sort of' looked like rust or like it was overheated or some harsh chemical spilled on it, yesterday I swung by the exhaust shop to show the manager & he said he wasnt sure, maybe it was simply a bad quality tip? He is aware I am a detail freak & asked what I polished/waxed it with. Everytime I would wax the truck (the wax I use is FK1000p hi temp wax...which also seems on par for an exhaust tip) and the only other liquids that would touch it would be soap,water or megiuiars UQ detailing spray. I am pretty sure none of these would cause the tarnishing, but If anyone has any suggestions how to maintain a stainless tip incase I am missing something or doing something wrong I would appreciate any ..tips, no pun intended :xyxthumbs: (PS they installed a new tip for me free of charge & I didnt even ask. Awesome shop.) ...another note, is the tip is a long way from the engine on this vehicle, so heat shouldn't be an issue either.
