Very nice bike you have there. I would caution against a repaint as rattle can never looks as good as the original paint. I think finding a set or decals for that bike might be tough too. To me a bike without decals is not complete in a way.

Also, I've been reading up here about rust removal techniques and there are a good number of threads here outlining products and procedures. You would be surprised at how well original finishes can turn out with the right tools and time. Good luck!
