I am cleaning up an IBM XT keyboard that has some minor dings and scrapes on the plastic top and metal bottom of the case. I would like to touch up these areas so that they no longer show, and I am seeking advice on painting techniques as well as the type and color of paint to use to match "IBM beige". If possible, I would like to avoid painting the entire surface, but either way, I would like the final result to look like a new keyboard rather than an old keyboard that has been painted. Thanks for any painting tips you would care to share!
