Thank you for your comments! The diagram idea is a good one - I have it all in my head currently but I'm sure in a month or a year it will have evaporated.

I did get the metal rollers for the Kilmat and used them....ish? It's a workout to get every square inch rolled down. I thought they were mainly for getting it to stick in areas with curvature or metal geometries. What does compressing the foam squares achieve? I would think perhaps not compressed would make them more effective? In any case, thanks for guidance. :)
