Why avoid BLO if one simply wants to shine up the finish? It doesn’t build up a finish, etc. I just know how well it’s worked for me on several Remington rifles built between ‘45 and ‘55 and on whatever finish they used before they went to their RKW finish
Now if you want to go with a completely new finish, have at it with a urethane mix..I like Permalyn and Permalyn filler (VERY thin right from the can)
