Rust Treatment of Exhaust Fixings - andrew4
Hi All

I have a 1991 VW Golf (81,000 miles, 1300cc).

I noticed that the exhaust clamps and bolts near the front of my car were rusting. I therefore applied some copper grease to them in order to delay the onset of rust.
I have now noticed that the copper grease has changed from a copper colour to black.
Is this due to the heat and have I been wasting my time?

Thanks
