I recently picked up a grease that is considered extreme duty and tenaciously tacky. The name is Purus ak60. It's a lithium complex that's GC LB rated. It is made with a heavier base oil. This is the tackiest grease I've ever seen. It makes long strings and almost takes effort to stretch it apart. I will try to post a link to the product below. My question is when is extreme tackiness helpful. I understand that it resists throw off and sticks to surfaces better. What about things like u joints, wheel bearings, tie rods ,loader pins and other regularly greased areas?
