I need to restore some chrome plated parts of my old bicycle. I cleaned and polished them but at some points the chrome has gone away. There is no rust, but they don't look as good as new... I know that the best solution is to chrome plate them again, but at this case it is more economic to buy new. I am thinking about painting them. Is there any special paint that has very good adhesion over chrome without using any primer? I have to say that I have to use a wrench on some of these parts in order to install them (headset and bottom bracket) and I am afraid that the paint will peel off... Any advice could be very helpful!
