I’m glad to hear you found it. Even the workers at my store weren’t aware of it when I asked. They had to look up the part number to find it. LOL.
My project ended up not requiring glue but I had planned on using the normal pvc bonding products made for pvc pipes. My understanding is that it actually chemically “melts” an outer layer of pvc so that the partner piece’s melted layer intermix when fitted and they become one piece after it cures. That being my understanding, I felt like those products would create the strongest bond. I’m sorry I can’t offer more than my thoughts on that. I never actually did a glue test.
My wife ended up painting and I think she used acrylics but we were in a rush at the time and just used what we had. If I were to do it again I would find a primer suitable for pvc before any final coats but what we used worked.
