If by coated you mean the entire rotor is the same finish like,
they give minimal protection and will start rusting in 6-12 months. Better are the painted rotors like,
the will stay nice looking for a few years depending on the environment. Price is generally a good indicator and you get what you pay for.
Those are a good choice.They are Wagner Rotors with E-Shield Black Coating
In a real road salt area, then painted are a joke. I've had best results with E coated like Raybestos or Powerstops. They don't eliminate rust but slow it down a lot.
I stand corrected. I thought the E was like Geomet or Element 3. Those type of coatings are the only ones to use IMO.Those are not E-coated rotors. Powerstop uses a Geomet coating, and Raybestos uses something similar.
E-coating is the black electrostatic finish and is used on Centric and Wagner E-coated rotors. The OP has Wagner coated rotors.
The real need is for the anti-corrosion coating on the vanes inside the cooling channels so they don't get blocked with rust over the years. Gott'a keep the cooling channels clear and keep the air flowing.
Now that Raybestos, Stop Tech, Centric, and other brake brands are owned by First Brands Group (private equity outfit? Also owns Trico & Anco wipers, Champion Labs filters) with most parts made in China, is the quality staying up where it used to be? Power Stop also uses Chinese parts...still good?
I stand corrected. I thought the E was like Geomet or Element 3. Those type of coatings are the only ones to use IMO.
The black coated rotors will be rusted within a monthI have to replace Rotors and Brake Pads and the new Rotors are Coated black and are wondering how well the black finish holds up . I was thinking of spraying on some CRC Corrosion Inhibitor for added protection . Is this necessary ?
