Today I discovered that my rusted OEM exhaust was really only a rust STAINED exhaust.
Here I what I started with:
Attachment 35232
Then I poured full strength Muratic Acid on it, let it sit for a minute, sanded with 320 grit, wiped the rust off, and repeated the process until the rust was gone. Then I wet sanded everything with 600 grit and a garden hose.
Here is the result:
Attachment 35233
So, I saved $615.00 today with 1 cup of acid, sandpaper, shop towels, and 4 hours of my time.
:woot:
For any others wanting to do this with acid, BE CAREFUL!!!!, make sure you do it outside, have breathing protection, thick rubber gloves, have a plastic /rubber pan to catch the acid in so you can use it again, and baking soda so you can neutralize the acid when you are done for disposal.
Cheers,
