Looking for guidance on how to revive the paint on the '37 Alvis. Definitely looking for a polish, not a wax. In the old days, there was something called T-Cut, but the modern T-Cut seems quite different. Amazon lists a product called Trinova Scratch and Swirl Remover. Any experience with this? Or could clay bar, which I've never used, work? Or start with 2,000 wet & dry? Sorry if this have been covered previously in detail. Have searched and found references to good old orange bottle Nu-Finish, but not much else. Thanks!
