I perfer bees wax for my table saw top... When I am not going to be using it for quite some time. (I used to use WD-40 when I didnt know any better and got surface rust). I use steel wool to take the bees wax off when going to do a project
Oldslowchevy is right PB BLASTER is the best for busting loose bolts.
I have also used 3 in 1 oil for lots of things, especially for squeaks, never for protecting a finish. If your going to do that, then ANY oil would be a good protecterant... Not recommended for table top saws in my opinion, as it leaves a film and has to be taken off with a solvent.
I have never heard of the other products either, so I cant give an opinion one way or another...
