I read the Rem Oil can, too. It says protectant and lubricant. The WD-40 can says protectant and lubricant. But yes, I've heard all the "horror" stories about WD-40. But, I think that it has more to do with it not being a "gun store" lubricant. Just seems shooters don't like it because it is readily available at any grocery store. I have a old Remington Mohawk 600 .243 that has not been cleaned with anything but WD-40 since we obtained it in 1980. There is not a speck of rust and bluing is 99%. Action is all original and fuctions perfect. Same goes for old police armory model 19 S&W .357 revolvers that have had 15,000rds + of cheap, dirty .38's through them. I still carry one on duty. Unless your gun is in a climate controlled environment(AC), it will get moisture and, as has been stated, it separates water from the metal. Rem Oil is good, but since I shoot their ammo I don't feel I need to spend anymore money on something that does not offer significant advantage, if any, over my grocery store WD-40 just because it has Teflon. Just my experience :-)
