I have a SPS varmint in 223 that I use mainly for coyote hunting. Gun is less than a year old, never seen rain or snow, gets coated in rem oil before and after each hunt, and still ends up covered in surface rust the day after I take it out. Anybody have any problems with newer remingtons rusting or know a way to stop it? I contacted Remington and naturally they don't cover it under warranty.
