And he was "more" familiar with the Da-Lite material?
Good luck then.
These words turned out to be prophetic. The screen material was very thin and "stretchy". It was very difficult to get all the wrinkles out. It took about two hours to install and could very easily have been ruined during the process if extreme care had not been taken.
I'll let you know the results after watching it a while. But in retrospect, I probably should've researched the PVC board more, uncertain. Since my buddy had never heard of it, I assumed it was not available at the nearby Lowe's or Home Depot. At least now there are no rollermarks or uneven spraying splotches to content with.
This is the follow up. After 8-9 months, I'm convinced this was the best way to go for me. No visible blemishes, reasonably inexpensive DIY solution. Installation is slightly tricky, you'll need more than one person. However the results are very good.
Parting with the CRT was sweet sorrow. It served me well for many years. Couldn't even give it away. But undo goo with screen fabric.
