Randy Clark of Hot Rods and Custom Stuff brought his 1966 Buick Riviera to Jay Leno’s Garage wearing a gold paint job that took his team fifteen hundred hours to complete — longer than most full restorations take start to finish. The Riviera’s clean, GT-inspired lines gave Clark’s crew the perfect canvas for that level of obsession. Even Leno, who has seen thousands of custom builds, wanted to know how anyone justifies that kind of time.
