So my seats take on water every time it rains and I have it uncovered. Since it is in the water full time it sits at an angle and all the water goes to the back of the bottom of the seats. One in particular takes on a lot of water. I plan on making some drain holes at the bottom (there are none there now). All is good with all the seats except one which is beside the side door. The outside is upholstered with felt and vinyl. If I drill holes on that seat I am sure to tear the vinyl. Has anyone run into this dilemma and if so, what was your fix?
