Is it elastic or hard like epoxy when cured?** A: 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. **Q: Would this work for adhering rubber matting to a wooden and aluminum boat deck?** A: yes, it would work. A permanent solution would be 3M 5200 sealant. Try a small piece first! **Q: can i use this to attach solar panels to camper roof? pnls weigh 24pnds.** A: I used mine for water proofing sealant while glueing down a metal flang which weighed very little. Not sure about the solar panels **Q: Would this work in a swimming pool. I have a concrete pool that has plexiglass windows in the sides below the water level.** A: I believe so, we use it on the seams of our water slide that's underwater at all times. ## Frequently Bought Together - Sikaflex-291 LOT, White, Marine Adhesive and sealant, General All-Purpose PU Adhesive with Long Open time, 10.1 fl. oz - Sikaflex-291, White, General All-Purpose Fast Cure Marine Adhesive and sealant.
