deep creep is good but I like pb better. I would go with pb. without that and without the acetylene torch, i woulda been screwed. also if heat is involved, you can use parafin wax since it doesn't blow up.

KROIL! hard to find a distributor though, gotta try your local HVAC supply houses, bearing distributors, or just order right from Kano labs. (and yes you can get a 55 gallon drum lol)
I've been using kroil for years. I've literally fought with a bearing on a shaft for days, hit it with some kroil, tension the puller and walk away. It WILL be on the ground when you get back. Plus it smells awesome, like victory over frozen bolts lol...oh and when I lifted my XJ that's spent it's last 17 years and 200k in the northeast salt I douched it with kroil every day for a week prior. Didn't break one bolt when taking her apart.
Bottom line, wd is water, pb is eh, liquid wrench sucks, kroil is the only one that's ever worked for me on the toughest bolts.

PB Blaster is ****.
Liquid Wrench is ****.
Kroil or BG In-Force.
I personally use BG cause its readily available at the garage. You can actually hear the frozen parts popping apart. After you use BG or Kroil the only thing you'll ever use PB for is filling up your trash can.

Seafoam deep creep hands down. It's more expensive but works way better than pb blast, which was all I used to use, and the fact it's designed to be used with heat makes it even more appealing to most.
Cheapest I've found it here is at menards for about 8$ a can and I know advance had it for like 12$....and IMHO it's worth every penny.
