I fell kind of lucky that the hard top I recently picked up is at least pretty close! (Ocean Blue metallic over Lapis Blue.)
To the original poster, I would favor leaving it in the current matte-black wrapping. It looks arguably a bit better than before, and also mimics on quick glance the matte-like black texture of a woven black fabric soft top.
Maybe we should start a "986 hard-top swap" thread...
If anyone in the Pacific Northwest has a lapis blue hardtop they want to swap for my ocean blue metallic, let me know!
mine also has the silver "S" ("titanium"? Lol!) beading around the rear window that I'd really ideally rather have in just black trim. (Maybe I can re-finish it black, or replace it...)
But overall, I really do like the look of the car a lot more than I thought I would with the hardtop actually on it.
