I think most of the old American companys put some kind of laquer on the case colors. Brownells sells a version called baking laquer that I used on a recase colored Charlin to protect the work Mr. Turnbull did. The problem with baking lacquer is getting it off, (not that I cared, I wanted a tough coating) but, carb cleaner (the soak kind, available at NAPA and other automotive parts stores) will take it off, and won't damage the colors. I've heard guys here say a coat of tru-oil is a nice, simple way to protect colors thats very easy to remove. Haven't tried that myself, but, it seems plausable. If you have the ability to dismantle a sidelock yourself, a coat of any version of spray can clear laquer would be better than nothing, a coat of baking laquer would be better than spray can stuff, (do you own a spray gun and a compressor?) and some tru-oil would likely be easiest. If you laid it on thin, the spray can version might not leach past the pins to gum up the works, but, I don't consider that to be the "right" way to do the job. The best adhesion would come with dismantling the gun, and proper de-greasing as well. A final thought, is that any coating is going to add a layer of sheen that purists will find objectionable-but, like I always say, purists didn't cut the check for the gun. This will likely only be a problem when you go to sell the gun, and wouldn't be a problem with many buyers. My old Darne has beautiful colors, which I did a baking laquer job on, but the years have removed some of the coating and colors from the high spots/edges on the gun. The effects of time can only be held off for so long...
Best,
Ted

For some time, I have been using a clear-coat aerosol spray-on lacquer made and sold by Behlens. It is a true cellulose lacquer that you can spray on and have a very uiform coat without bubbles and running with just a little care in application. When you need to redo it, it can easily be removed by merely soaking the parts in acetone. I have been very pleasedd with it's performance and I use it on all Damascus barrels that I refinish and on some guns that I color caseharden if the owner wants a protective coating.
Whatever you use, I recommend that you completely strip the internal parts and degrease carefully before applying the protective coating. You will then need to lubricate the appropriate parts and places when you reassemble.
