Grey (zinc?) coated OEM rotors...what's the consensus on how to handle?

[brimstn]

I'm upgrading my brakes to the GT calipers/rotors and got my new OEM rotors today. They're coated in a gray substance, presumably zinc to keep them from rusting.

I've searched the internet some and opinions seem to be divided: Take it off with brake cleaner prior to install vs. leave it on and the pads will remove it over time.

I'd be fine with leaving it on, I just don't like to think of that stuff possibly gunking up my new pads. Any thoughts from you guys?

I left it on. There is no way your pads will gunk after a proper bedding in of the rotors.

Thanks for the input. That was actually my second question...what is the proper bedding/burnishin procedure for OEM pads? I can't find anything for OEM pads, only aftermarkets like Hawk, etc.

45 hard/moderate stops to 10-15 a few times?
