My 62 convert is not in as nice shape but I am keeping it a survivor with no repaint. The interior paint was pretty oxidized (convert) with some bubbles here and there. I used a very fine polishing compound by hand and then paste wax and it came up very nicely. Even used Eastwood clear Rust encapsulator on the rear trim panels for the quarter windows after a 1200 grit sanding to remove some surface rust and it came out OK, not restoration quality but it’s a survivor and looks good. Your coupe should come out nice.
