I used napa premium rotors and they warped after 3k miles.
This is not a flaw of rotors if this happens. Cast iron will develop surface rust just from the humidity in the air alone. It looks bad but isn't fatal and the pads will remove that coat of rust the first time you apply the brakes. On the hat, O.D. edge, etc, the rust will remain.I've had uncoated rotors completely rust over in a day

It's just hideous, but it won't cause them to... warp.This is not a flaw of rotors if this happens. Cast iron will develop surface rust just from the humidity in the air alone.

Not as much of an issue as you may see on videos you watch (SMA) or something that can't be avoided quite easily. I live in the rust belt too.And the rotor will freeze to the hub and the wheel. This is why it's impossible to remove the old rotors without a hammer
