I agree with Tiny and Jay,
If the car is a driver and re-chroming is not feasible or whatever, then the paint may be an option.
When you do bite the bullet and get it re-chromed, it is important to pick a reputable company to do the job. Remember: You get the quality you pay for and high quality and lasting chrome wile initially not cheap, is the best way to go in the long run.
Last week I sent off a locking gas cap to Paul's because I have seen their work, used them before and trust them to do the best job on what you send them. Not cheap but quoted charge in the instant case is very reasonable considering the condition of the cap (grip edging not up to par. Note: Some other companies do quality work as well. You might want to ask informed friends whose opinion you respect and then go with their recommendation.
If your car is a 37 or 38 and/or has an outside sun visor installed then I think the paint option may be the way to go. Some things can't be improved upon. You know. (Outside sun visors on early 50s are an exception.)
Good luck with whatever you decide to do,
Charlie
