I wonder if you'd ever be able to recapture that color scheme and decals. I'd guess that "look" would be loss forever once you start sanding and preparing the frame.
Yet.... I've always wanted to do a re-paint myself! I do understand the attraction. The bike has lots of shinny parts... so a one bold (or bright) solid color paint job could be real appealing. Still lots of warm weather left.... to allow for a frame to sit and cure to a hard finish... clear coat included.
