Will this work to repair cracks in my pool skimmer? Is it elastic or hard like epoxy when cured?

It is elastomeric and should work well for that I would think. I used it to seal the roof seams on a 2015 GMC pickup and it worked great. Keep in mind it is self leveling so it spreads out a bit on its own.

Would this work for adhering rubber matting to a wooden and aluminum boat deck?

yes, it would work. A permanent solution would be 3M 5200 sealant. Try a small piece first!

can i use this to attach solar panels to camper roof? pnls weigh 24pnds.

I used mine for water proofing sealant while glueing down a metal flang which weighed very little. Not sure about the solar panels

Would this work in a swimming pool. I have a concrete pool that has plexiglass windows in the sides below the water level.

I believe so, we use it on the seams of our water slide that's underwater at all times.
