Title says it all.

I was about to buy a set of replacement wheel nuts for 80 pounds, but before I did I bought a can of Rust Preventing Chrome enamel spray paint and it worked a treat!

I know I should have taken then all of and sanded, dipped in enamel, but I simply cut a hole in some cardboard, held it over the nut and sprayed.
It looks 100% better and only took 5 mins. (Although I think a funnel would be better than the cardboard I used)
