Bill,
This is a truly amazing response. Thanks for all the leg work on the data gathering. I'm going to grab some Kilz2 and get moving. I rolled the polywall on the floor the first time. Do you think I can roll it while it's tacked up on the wall? It will be easier for me with 2 young kids around

I don't want to get any runs. I think I used a 1/4" nap roller before. Any recommendations?
I don't mind watching the Kilz2 for a while until the Black Widow is perfected a little more. This will also allow me to search for a bigger piece of laminate. I'm thinking a 5x10 piece.
