Semi-Chrome has been suggested by multiple people but I am leery. I used it on my Repro and ended up with a receiver that looked like chrome. A leather pad and elbow grease seems like a reasonable method most like normal wear.

Theres a lot of good advice here ,some from years of hands on experience ,some personal opinion and were each entitled to our own ....I won't add my two cent's worth on the matter the base has pretty much been covered,slow and steady is the key word (and that would be my advice /opinion ;)) but if you still would like more info why not contact Brad Bachelder ? I have never found him anything else other than helpful and obliging ,a true credit ...and to be sure if anyone has experience with this it would be him .

I purchased a new CSMC Fox about 16 years ago. I have carried the gun in the uplands about 10-15 days per year. The case colors are 20-30% gone.
I have a friend that had a early A Fox re-cased by Doug Turnbull 15 years ago and he has shot gun in the field moderately. I defy anyone to tell me that gun was re-colored---it's scary how original it appears. So I say use it and the brilliant colors will become muted before you know it. Craig

Thank you all for your responses and help. I think I am Leaning towards the Semi-chrome, and will use it very sparingly. The suggestion of using leather to rub out the muddy colors also sounds good. Perhaps I will use a combination of both methods. I will post the results in a few weeks/months depending upon how quickly I achieve the results I'm looking for.

Is this going to be a "using" gun or a safe queen? If it is the former just take in afield, have fun and let nature take it's course. Once you have the right look apply a couple coats of clear lacquer and the colors won't wear any farther.

I'll be using this gun, but not enough to wear down the colors. They are very dark and thick looking, but sitting in the basement rubbing a gun with leather is still better than whats on my Honey-do list.

Another one of those times when a LOT more thumbs up's would be appropriate!
