I am restoring my 1990 Specialized Hard Rock, not sure if it counts as vintage...it is almost 19 years old...
I should have taken pictures along the way but alas I did not. It was an ugly greenish gold with purple decals when I got it and rusted on the stays and some on the fork, headset, stem, seat post, and bottom bracket. I have sanded most of the paint off of the frame and fork, only have the braze-ons and the tiny hard to reach places left to strip. I am thinking of getting chemical stripper for those parts.
Then I was originally going to leave it the raw steel with clear coats, because I kind of like that look, but now I think I may actually re-paint it (I have seen some pretty inspiring Rattle Jobs). I have repacked the bottom bracket and headset. I bought used Bontrager Racing wheel to replace the busted original busted alloy wheel. I was going to make it a single speed, but I am thinking of making it geared now, since I have acquired new shifters.
It is a work in progress...
