Thanks guys! Probably should have been more clear but the PVC panels were painted which I think was my problem.

Did a quick test over the weekend with PVC cement, CA glue and VHB tape on a painted PVC panel. The VHB tape won hands down. The others peeled off with the paint very easily. The VHB was very hard to pull apart and didn't peel up the paint.

My only concern is how the VHB will last over time outside. I've had the tape awhile and not sure what it's specs are?

Past 15 years now we've been using the Loctite PL Construction adhesive. Spend a little more on the 8X version and it dries in 1.5 hour. And hope you don't ever need to take anything apart. You will destroy it trying. And to be doubly sure, rough sand both surfaces for enhanced superpower bonding.
