I recently detailed a black C5 and spend
8 hours trying to figure out the 'vettes paint. I thought I was going mad. I got some priceless help from several on this thread and MOL.
Simply put: Corvette paint is
very hard - that is, it requires a lot of aggressive polishing to remove defects. However, to use Mike Phillips term, it's
scratch-sensitive. That means that IF you manage to remove the swirls/scratches, the polish will leave micro-marring, especially on the curves. That's what I was battling with. I tried
everything in my arsenal, from Megs to Menzerna to SSRs to 1Z to 3M. I managed to remove the bad stuff with an orange pad/Menz PG/BO6040 polisher.
The
real battle began when I tried to refine the finish. Everything I used, no matter how much time I allowed to break the polish down, left micro-marring. I even tried the famous Menz ceramiclear polishes. It appeared to leave a beautiful finish. IPA wipe-down to remove the lubricating oils...marring still there! The oils where dramatically filling the marring. It looked perfect, glossy, dark black...until IPA.
Long story short: the only thing that broke down enough not to leave marring on the scratch-sensetive paint was the ol' faithful...#80. :up
It took me 40 hours to do it; the same time it took me on the stretched Hummer H2.
Here's a photo of the two:
