Post if you find a re-chromer that charges a makes-sense-to-do cost. One of my cabin top winches is a great working Barient self-tailer. But much of the chrome has worn through exposing the bronze casting underneath. Looks like rust spots all over. Polishing helps for only a short while.
In the San Francisco Bay area, re-chroming cost when I've checked doesn't make sense to me solely for winch beautification reasons. Gone are the days when re-chroming was a common thing for car bumpers and hub caps, etc. Now only serious car or motorcycle restoration specialists or hobbyists have need. Also environmental compliance adds a lot of expense and time for the electroplating company.
Powder coating is another option?
