Full Metal Jacket Trap Dye - A clear dip that wears like iron. After 24 hours Full Metal Jacket is odor free. It is a trap dip for predator traps, land body grip traps and snares. You can use this dip in the water too, but will get a milky color. It will still protect and seal in the metal from rust in the water, but you will need to scrape your trigger and dog.
