Rotor coating

[darkcherrymetallic]

So I was inspecting my brake system yesterday to see if I need to replace my brake pads and I was amazed by the rust in the rotor vanes. I took a screw driver and scrapped the inside and pieces of metal rust were just falling off like crazy. There are some areas where it felt kind of thin to me so I have decided to just replace my rotors. My question is...I would like something with a corossion resistant coating. The two that I found online are NAPA's ultra premium rotors with onyx guard corrosion resistant coating or rotors on eBay with e-coating. I was able to find much more information about e-coating than NAPA's onyx coating. For those of you have used NAPA's ultra premium rotors with the onyx coating, can you tell me if it helps at all? The only information I found online was a person stating that the onyx coating did not help at all. If so, I was thinking of going with rotors with black e-coating. What do you guys think?

they are going to rust eventually anyways. the rust from the non coated part ( pad contact area) will eventually creep under the parts that are protected. They will look a lot better for a longer period of time though. I need some front rotors also, I too was looking into the e-coated ones.
