I have tried using many different finishes in my learning process and to be honest the best one I have found so far is the old school mix I made myself. Melted parafin wax, bees wax, and some oil together then let it cool. Once it cooled it was similer to sno-seal (which I also really like). It leaves a very nice mellow sheen and can be reapplied as necessary over time. If you dont feel like making it yourself then you can get several similer items on line or locally. Ones that seem to work really well are picards leather dressing, sno-seal, bees natural. I use to play with trying to use a sealer per say but found these protect the leather, look really good, and are relatively easy to use.
