I finally purchased some Catch All floormats for the front and rear of my '03 Crew Cab, and have questions about the location of the holes for the carpet grips. Each of the mats seems to have one of the holes at the floor mat low point. It would seem to me that water would collect at this area and leak onto my carpeting. I'm thinking about using some clear silicone to seal off this one hole on each mat. Anybody else had problems with this?
