..... I'm just thankful none of you think WD-40 is a penetrating oil

I have most of what you guys mention. PBblaster, Aero-Kroil, Sili-Kroil, liquid wrench and some AFT but out of acetone. Tried a few others but MY favorite is Aero-Kroil so that's what I use.
....so you guys do the same. Use what works for you.
Break time is over, lets get back to work!
