Decided to refinish the stock on my wife's Model 70 XTR Sporter 270, made in 1973. I think the plastic finish on the stock was called Win-Tuff, but I'm not sure. However, the coating IS tough. As usually, I start by scraping off as much finish as I can with several thin sharp blades, one straight, one curved. Man, this stuff is durable. 36 years old and still good. But, I like an oil type finish, so... I shy away from using finish removers, but I might do so in this case. Now, to find a good polyurethane finish remover. What a fun project. Well, at least the glass-bedding came out just right.
