Another one that I have use and like is
Aero Kroil, I was very pleased with this one. The only reason I don't still use it is it is not avalable localy anymore. I have new one that I have not tried yet, Mouse Milk it comes in a non arosol bottle. Yes I laughed at the name, the guy said you will be impressed, I don't know yet. My personal oppinion for the tough ones the GM or Mopar is the best. I personally feel PB Blaster and WD 40 are a waste of money if you plan to use them for serious penitrating. I am sure they are good for something. Just my thought one past experiances.
