What did you do with the snaps that are screwed into the floor? did you take them out? If not can you feel/see the bumps them under the carpet?

I had one snap that was in a center portion of the cockpit; under a bolster. The rest were on the perimeter. I filled the one hole in the center with 4200, and left the rest of them right were they were. You cannot tell they are there at all.
