If I was doing a full restore I would get it rechromed and professionally painted. If you are painting it yourself (which I am doing with the Legnano that just found it's way into my garage), I would try to make the chrome look as good as possible (polish, AL foil, and potentially the chrome paint pen). Unless I know for sure it's a "lifetime" bike, I won't pull the trigger on paying for the paint or the chrome work. I usually don't know if the bike is a "keeper" for a couple of years so I make it look as good as I can then I'll decide down the road.
