The first stock I refinished (old Remington 11-48) I used a satin, spray varathane like this one;

The last 2 stocks I've done (both 870 stock sets) I used this product;

I work for a company that does commercial millwork, has a full finishing dept., etc...so I have access to basically anything. However, in speaking to a rep for one of the companies that sells US stuff, I told him what I was doing...he asked if I'd ever tried the "Pour-N-Wipe". This rep had over 25 years of finishing experience, and yet used this for his own personal projects. He gave me a part can, I did a 1951 Wingmaster stock set..and the results were superb. I subsequently did a stock set for a friend using it...now I'm stripping an old stock set for one of my other shotguns...and plan on using it for that too.
