Review on Liquid Wrench L666 Lithium Grease by Wagner Witlin

I use this in fairly large amounts on my pipe bender to keep the aluminum legs on the trigger. I've had at least 3 cans that just stopped spraying when there was still a lot of product in them. Replacing the tips didn't do anything so it's not a clogged tip and these aren't jars that were used then left and later reused - rather they were used from start to finish in one day so it's EXTREMELY unlikely that something has "dried up" and clogged. I'm switching to another brand, I can't keep wasting money, and I can no longer trust that I have enough money to complete a project when I don't know how much each new can is actually bringing me.
