Will this tape work to repair a heavy duty polyethylene tarp?

Temporarily, but sufficient movement, dust, etc. will likely cause it to loosen over time. Consider sealing the edges with”paint on” “flex seal”.

Will it work on a leaky pipe in the bathroom?

Hi there, While this tape would work for your situation, for a leaky pipe in the bathroom I would recommend our Powersteel Duct Tape. That tape is some of the strongest tape you'll ever lay your hands on and will clearly up any leaky pipe you have. Thank you Eric Gaffer Power

Will this stick to rubber?

Hi there, Thank you for your question. Yes this type of adhesive is meant to stick to most rubber material. We also guarantee all our products so if you were not satisfied we'd offer you a full refund. Thank you, Eric Gaffer Power

could i use this to protect the joists under my decking?

I used the tape to hold down roof tile until I could replace my roof. I would not think tape would be strong enough to protect deck joists unless you want to keep mold or insects from harming the joists. If you are using the tape for support to with stand a large crowd or heavy loads. I would replace the joists for safety reasons.
