Many of my revolvers are post-war, pre-1957 vintage. They are all original, high grade shooters. One thing about them that is bothersome to me is the shrinkage of the wooden target stocks (due to age) to the point of where there is a bit of wiggle in the fit. Years ago when I discovered Ballistol, I started using it for cleaning, lubrication, and rust protection. I've also found it to be a good protectant for wood. One thing I discovered is that it rehydrated the wood and expanded it enough to tighten up the fit and eliminate the movement. It does not split or crack the wood, nor does it affect the finish. It's also a great cleaner with a toothbrush on checkered stocks. The Ballistol is safe, has almost no odor and has a wide array of other uses. It's not the be all, end all for gun maintenance, but It's a very handy substance. In the interest of full disclosure, I have no connection with the company.
