S90: PB Blaster vs Liquid Wrench, Round One

So I've heard good things about PB Blaster, good things about Liquid Wrench, and great things about Kroil (except for its price).  But the local shops only seem to carry PB Blaster and Liquid Wrench, so I decided to let those two duel it out first.

A couple days ago I sprayed every rusty nut and bolt on the left side of the S90 with PB Blaster, and everything on the right side with Liquid Wrench.

Today was the first test of their effectiveness as I went to remove the seat.  You'll see the bolt in question at the top of the picture below (it's the smaller one).

But Round One turns out to be... a Draw!  Shockingly, I unscrewed the nuts on both sides by hand.  They were so loose I could almost spin them.  I suppose there's a chance that they could have been that loose to begin with, but just looking at their condition I find that very hard to believe.

Instead I'm really hoping that it was the rust eaters doing their job, and doing it very very well.
