As I was tearing out my old layout, I noticed that everything came off of my blue extruded foam rather easily. I was using white latex caulk to put the roadbed on the foam, and the clear latex to place the track to the roadbed (that would NOT come off without a fight). My foam has about a 1 mil clear coating on it. So, I'm wondering if that coating should come off or not before putting any latex caulk down.
Has anyone had experience with this?
