I have NEVER had any grip, stock, finish ruined by Rig #2 Oil. Rig #2 Oil has been my go to for 40 years. I use it for cleaning, as a rust preventative and lubricant - works very well and the carrier evaporates soon after applying leaving a non dust attracting layer of lube & protection behind. Also GREAT for the inside of firearms as it won't attract dust and debris.
