Unless the paint is really toasted, you might want to ask yourself
Should I Paint My Bicycle? You might be surprised at some of the pros, and cons of doing so.
The Raleigh Superbe is a collectable bicycle and increasing in value all the time. Yours looks to be well worth the price you paid and, were I you, I would get it on the road, ensuring it is safe and dependable to ride, and then ride it for a while. Make your cosmetic decisions after you get to know the bicycle.
If the bike is to your ride liking and you still feel that the cosmetic face lift is in order, then go for the paint job. One thing, though, you might want to ask yourself if the rest of the bike will match that shiny new paint. This has always been a problem for me when considering a repaint.
Anyway, good luck with the bike. They make pretty darn good commuters, in my opinion.
