Can I use it around the base of my toilet?

You can! We recommend keeping it near the base of the toilet and not spreading it through the floor as it can become slippery when wet. Let us know how the project goes!

can flex glue be used to repair a roho inflatable neoprene wheelchair cushion?

not sure, they make a tape like duct tape, that might work. The paste is more for sealing cracks.

can you paint after this is applied?

Spray paint might eat the rubber away or anything else that has more of a solvent when you paint I wouldn’t use on this

Will it fix a hole puncture on a 8” subwoofer?

Yes read my post about the puncture on my 2016 ford interceptor rear quarter panel worked like a champ on this damage from a corner of a shelf on the wall
