Resorting an exhaust
 
Hey guys,

On the car I have the previous owner has a Greddy SP2 on it. Obviously, the guy let his car sit outside rain,snow,shine,sleet you get the picture. Well the exhaust is oxidized. So instead of having a nice polished finish like they come with it is dull and some parts are yellowed which others (welds) are starting to rust.

I was wondering, I was thinking of going 100/220 sanding the exhaust then paint the tubing of the exhaust black with high temp paint and then trying and re-polishing the canister.

Does anyone have any tips for me? In my mind I should have the canister polished before I start painting or else I could end up with a PITA.

Thanks,

Alex

there are many polishes on the market designed to restore oxidized metal. Painting would be a good option too but youre goinbg to want to use a bit higher grit.

I've restored a number of exhausts. Here's a few tips -

First off, get some Castrol Super Clean and a sponge and clean it thoroughly. Wet it down, spray on super clean, rub with sponge, hose off, repeat.

Next, get some Chrome Polish and a rag, and start buffing. With some elbow grease, you'd be amazed at how much crap will come off and how good it can look.

If you want to go high-tech, get that new Mother's Powerball. Put it on a drill and go to work. Even better, get some stainless steel cleaner (I found a spray cleaner for stainless appliances in the cleaners aisle at the grocery store) - spray that on, buff it with the Powerball, there ya go.

I have taken VERY tired, crappy looking exhausts and buffed them up to damn near new. Clean and polish before you fool with sandpaper and the like.

Thanks guys for chimming in.

I got some Mother's Aluminium and Mag polish. I am going to take a look at that stainless cleaner if it doesn't work. Although I don't have a Powerball I have a random orbital polisher which I am going to try.

What is this Castrol super clean?
