^It's funny you mention that. After I bought the WD-40, I did a few searches on the Internet and found mention of the PB Blaster all over the place. EVERYWHERE I saw it mentioned with WD-40, the reviewer/commenter/poster was saying that WD-40 didn't compare to it in terms of penetrating power. Most said WD-40 flat out sucked. I saw the PB Blaster earlier in the store as I was picking up the WD-40 reading the "As seen on TV" label thinking to myself "That stuff probably sucks.". I guess I was wrong. I returned the WD-40 about 3.5 hours after I bought it and picked up the PB Blaster.
I'm going to try with the PB blaster solo first assuming I can still get my socket to somewhat grab that nut and then if that doesn't work, I'll try using those bolt extractors you mention. In fact, I'm going to probably buy some just in case anyway cause I'm sure I'll need to use them sometime in the future. That's the first time I've ever seen such a thing. Thanks for the advice!
