Hi, I have new reproduction '65 GT350 wheels (cast aluminum center, steel rim) I bought from Branda for my '65 Clone. Anyone using these wheels? I'm wondering if I should coat them with a clearcoat or something to protect them...do you recommend anything for these wheels? I've done a search on wheel coatings relating to other wheels, but I don't know if I should treat these differently because of the cast centers. Thanks!
