Wow, Ben, you actually bought something that didn't need refinishing!
Henry rifles, "Made in the USA or not at all". By golly. Now, if they'd make a brass receiver option for, say $100 more, I might have one. I just can't abide black paint next to all that other beautiful blued steel and Walnut.
Those Model 06 Winchesters are really neat, I have a take-down version with something like minus 20% of the original finish but no real rust issues or action wear, it's tight as a drum and will cycle empties. It simply dotes on heavy subsonic LR ammo.
