If you can get some stainless bolts, they might be a bit more expensive but chrome finishes no matter how good or bad are going to deteriorate.

In the long run I think I'm going to invest in a case tumbler and strip the chrome off mine completely and just leave them bare to be removed and polished whenever needed, makes more sense than stressing out over rusty chrome and having to replace them. I have replacement OZ bolts there I'm just reluctant to use them because I know they will look crap before long.

Your man who owns that shop sold Bart his BBS fyi, I think torquepartz do stainless bolts
