I know the animal is suppose to be a high load particle. Im not sure what the weapon is. I actually have taken the polish off my animal but still havent had a chance to use it on some real grease. Although mine is drilled with the pin right next to the ring finger maybe a hair above them, with everything stacked below it. Im not sure how that drill will work on some oil though. I was thinking of getting another weapon depending on how well the animal will handle some oil.
