how long does a zinc-plated rotor normally keep it's appearance?
also, can you re-plated it after it's been plated before?
what is the benefit of zinc? (higher heat tolerance, improved appearance, or both)

1994SubaruSVX:
did you have a problem with warping before you had your rotors/pads replaced? i ask this because there are those out there with stock rotors and zero warpage, while others have stock rotors and a ton of warpage....possibly stemming from other issues.

thanks for the input.
