Those that are following this topic will see my pics on page 1. The Bullet and the Zilla both saw somewhat equal amounts of water and methanol over the last year. At least that'* what we assume by discussing our frequency of use and testing.
Paul, from what I've seen of them (having both types here at different times), they're the same. I'd assume yours would be some type of application defect. Not cleaning the rotors as well before yours were coated, rather than a difference in coating.
Or perhaps curing temperature or time after application.
If it blows oil out the snout, the snout is pressurizing due to leaks in one or both seals in the rotor assembly bearing plate. That'* the only reason (other than extreme boost overcoming those seals).
