Yeah, there is no real cut-off where the lip stops and where the black paint would begin. It's going to be a PITA.
I was planning on using VHT Polyurethane, supposed to be good stuff.
Mysticz had some SE wheels black chromed with the lip left silver. They came out super. I contacted a wheel guy here in Denver and he quoted me $125 per wheel for powder coating. Rediculous!
I hear ya about after market wheels. I keep looking, but every time I see a set I like they either don't make them for 6 studs or have the wrong off-set.
Still considering options, but I think the Sequoia/Tundra wheels would look awesome IF done right.
