Found my noodles at the dollar store today and was trying to unbolt my first victim. The bolts in the front of the seat came out easily and the ones in the rear won't even turn. What would be the best tool to use to get those suckers to turn and come? Should I put WD-40 on them? I was using a ratchet-screwdriver handle combination and not sure if that's too little torque.

So what wrench should I use and/or lube to get that thing to turn. There's no rust to be seen but she's an old girl.
