I was able to get several of the painted panels installed yesterday afternoon. It is a huge pain in the ass to cut around all of the notches and outlets but it will be worth it.
The large room is most of the way done, I have about 10 feet of one wall to do, and a few offcuts. I will save the offcuts until I have the other room done as well in case I use some of the scrap. No sense using good stuff until you have to.
