I put aftermarket wheels on my truck about two years ago and only about 17,000 miles ago and every single one of the black lug nuts is rusting.

Is there some kind of black lugnut for aftermarket wheels that will at least go 10 years or so w/out rusting?

 

I don't know about your 10 year plan, but this thread discusses them.

Im on set 2 of the black ones, one set from ebay and another from my rim shop, both are rusted.

I didnt see any mention of the gorillas not rusting. If thats the case with them ill be ordering some

 

I ordered another cheap set from Amazon. I guess I'll see how long these last. Sad that there's no "black chrome" or some other hard coating that could be used...
