sparkles now shine (metalflake salvation)
The metalflake stripe on my '78 S&S had oxidized so badly that the flakes were exposed on the surface and it was no longer possible to bring back any gloss, so I decided to lay on a protective (and glossy) coating over top to protect the flakes. I wetsanded carefully one last time (400 then 600 grit), masked everything, then sprayed on 4 coats of automotive 2 part urethane. I can't believe how well it restored the sparkle of the flakes, as well as the color! Hopefully having the protective coating will prevent any further degradation of the original surface, and will keep it glossy for years to come. New vinyl (correct font, finally!) to be cut and applied shortly.
