Got 8 Skyline calipers (total 16 pieces) done for a carton of Corona, they came up perfect, just needed to be rubbed back in a slightly finer sandpaper (1000 grit, then I used more all the way up to 2000 grit)
Perfect for pre-anodizing job.
(NOTE: recommended you get new seals after sandblasting....mine appear to be all intact but I'll be getting them replaced anyway as there's no way to be sure how they hold up under the blasting)
