Anyone here use “never rot” cellular PVC molding? What glue or caulk do you use in miters and for joining moldings together? This stuff looks pretty good for plastic. I’m thinking of using it for vinyl window installations.

I used this to hide the gap between the top tile and the ceiling in one of our showers. Used a bit of silicon caulk on the miters. After 5 years it looks no different than the day I put it up.
Just one data point.

Used it in a half bath around the floor. Took paint fine and I used regular (paintable) caulk for the joints. Looks good two years later. Careful though, it cracks easy if you put a nail to close to the edge (experience speaking).
I use PCV pipe cement. You can get longer working time by chilling the can.
They also sell a PVC cement for assembling shower enclosures that has a longer open time. I use that for trickier layups, though it has a greenish color that might not be desirable if you are not painting it.
Once assembled, it is monolithic.
I have not yet tried the Gorilla Glue PVC cement, but the instructions say it takes far too long to set.
I've replicated some window sills, and water tables so far. The stuff is great to work with. You can fill holes with a mixture of PVC 'sawdust' and cement, or bondo.
