Lucky for me, I scored a Waterford, complete with Campy ten speed group, last Summer, at a Yard Sale. The bike is less than pristine, cosmetically speaking, but not too bad. I have absolutely no intention of painting it. Of course, as some Forum members might already know, I believe, strongly, in maintain "original" as long as possible. My Legnano might get painted - someday...
Before you do decide on a repaint, you might want to consider all, or some, of those things that have crossed my mind, over the years. If you wish, take the time to have a look at
Should I Paint My Bicycle? Perhaps that will offer some, previously, unforeseen things to consider.
