Tire mounting lubricant in paste form. This stuff is amazing. A little dab of this brown goo smeared on the tire bead and your tire will easily slide onto the rim. Seating the bead onto the rim no longer requires obscene amounts of pressure. Convenient 1 pint jar is enough to mount dozens of tires. Vegetable based and non-toxic, washes with water and inhibits rust. Can be mixed with water and sprayed, or used straight up. Made in USA.
