Part store strike out

I hate these box auto parts stores!!! If they cant look it up on a computer, they have no clue. I went looking for some gear marking compound to set up a ring and pinion a couple weeks ago and, not one parts store had any and, most of them didnt know what i was talking about. I went to Dollar General and bought some Desitin diaper rash paste and, set the damn thing up....lol
At least the rear end won't burn and itch...
