Ooh! no I can't help. But I feel your pain, as my 16 year old GRiSO's lovely wheels are also just starting to bubble in a couple of spots. The rest of it seems to have survived the all-year use in and around the salted roads within the magic circle that is the M25. UK winters are comparatively mild, but it gets icy enough at times for the roads to be salted- so bikes do take some punishment. So I too am thinking of having them refurbished but don't know where to start.
