isn't there a type of black that doesn't fade to purple?
also, was thinking about that process for the rearsets?
I've read several things that say the hard ano won't fade.
I can tell you with first hand experiance it will eventually. Maybe the guy I use isn't doing the process correctly, but the last nakid bike I had with black ano'd forks ended up with dark purple forks in the sun after maybe a year or 2.
Whatever ducati used stock on my rearsets has turned a greyish color....but I'm fixing that
