wheel scuff

[Only4U]

earlier today i noticed i had got my wheel knicked by something...a rock or something of the sort. anyway, the scuff it made chipped a very small bit of metal off of my wheel and didn't make a very big mark, but i noticed there was no metal there. should i worry about this spreading and causing all of the metal to crack and peel off? should i get some sort of protective enamel stuff to put on there, or is this no big deal and will turn into anything more than just a scuff? thx.

I scratched 1 of my chrome rims last week just put some wax on it just incase of rust. Not sure if this is what your tlaking about.
