Rear wheel was a nightmare. They put the decal right on the carbon/epoxy layer, then clear coat over. Front had some clear, then decal, then clear. So I had to grind it out with brute force and left some deep scratches from the emory cloth, then hit it with 150 and 400 wet to smooth it before clear coating.
Used some Vaspar satin clear coat with UV blocking properties out of the can. Since I emailed a pro carbon frame repair place, the guy was nice and said it was a home job, and not for them, and said what I was doing was completely fine. They basically do the same thing in the shop.
