Ok, I could use some advise, process, steps. I tried putting in the carpet on the lower panel. I sprayed both panel and carpet and used a plastic edge to smooth out and get into the edges nice and tight. That worked ok. My issue came when I used a razor blade to trim the excess. When it was done It seemed to shrink away from edge and I had gaps. My question is did I maybe trim too soon so glue not set up 100% or is my process flawed?
