Question on painting / plating rotors. What kind of paint / material are you guys using on your rotors to prevent the rusting (VHT, zinc plating)? It seems some people had concerns that certain materials would prevent proper heat dissipation (especially on the track). What's the deal? Remember seeing a thread on this. Of course, can't find it. Search sucks! Really! Or mayber I do. Or both. Anyways. So, what can I use? Tnks.
