Doesn't work on perforated rotors
July 23, 2015
While this might work on standard rotors; it has no effect on perforated (drilled) rotors. There was still a large amount of flash rusting despite following the directions to the letter and using copious amounts of the product.
I had been so excited to use this product after seeing the advertisements; however I will never use it again as I am still left having to hand clean each wheel from the rust "fling" that I get despite the use of "Hyde's Serum Rust Stopper." This was used on a 2013 BMW M5 and was an epic fail. I'm not going to bother using it on my other vehicle since I don't get the flash rust issue like I do on the high performance rotors (no, they are not ceramic).
Pros:I haven't personally experienced any
Cons:Does not work on perforated, cross drilled rotors
