I have a set of Rennline studs. I change out my wheels a few times a year. I have noticed that the studs are developing surface rust on the ends.

Anyone else have this and recommend a product to prevent?

I have Porsche Motorsport studs and they're rusty too after this winter. I'll wire brush them and see if that helps. Not sure that painting them in Hammerite will help.

They're black oxide coated. Hit them with a wire brush or steel wool to take the rust off and put some light oil on them. The oxide layer absorbs the oil and prevents rust. Avoid cleaning them with anything that will remove that oil and they'll stay rust free.

Thanks for this. A good suggestion.

If an option, switch to World Motorsports Titanium as I think they now offer a stud kit as well as their lug nuts and lug bolts, but not 100% certain on that.

I use their bolts and nuts on both my 997s and the Cayenne.
