Is this any good for sticking treadmaster/rubber anti slip deck sheets on a boat?

Suitability will depend on the rubber unfortunately, would check with the sheet manufacture for the type of adhesive to be used.

Will this stick wood to polypropolene plastic?

Hi, no this is not suitable for polypropylene unfortunately.

is this suitable to repair a small tear in an above ground swimming pool

No reason for it not to work, I use it all the time to water proof my boat.
