A little off topic but I just tried a new method of getting to cosmo out of the stock of my M1 that came in last month and it worked the best I have ever seen. I took the wood and wrapped it in paper and then in a black trash bag and taped the bag tight to the stock. I left it in the rear window of my car (it didn't look to strange so that it was screaming "gun part") for two days. When I unwrapped it all the cosmo was out and in the paper towels and it looked real nice and still had the "patina" that we look for. I found this method on another board and felt I would share. Best method I have used so far with no danger to the stock and little to no mess.
yes works well doesnt it. Armorer's Corner - Wood Cleaning Article this is the write up from the cmp Section #9 also works very well. I love tung oil!
