I have a 48 cm Rossin that I will be putting up for sale shortly:

It has a really neat paint job. It clearly states that it has Dupont paint. In my case the frame was painted a kaleidoscope scheme and then peel off decals were put on halfhazardly over the frame and then painted white over top and then had the decals removed.
BTW, I picked this bike up in Italy and it was therefore painted in Italy.
