[recycled sixtie]

obvious? I dropped a mag wheel on the concrete garage floor. I was planning on selling the four Lexus mags which I do not need anymore. Can you have a crack in it and not be obvious to the naked eye? Does a tire have to be put on it first to see if there is a slow leak in it? Or is there a special spray that I can use which would emphasize if there is a crack?

Thanks all,
Guy
