I replaced both water fills and the cable hookup on ours last week due to aging plastic. The three new pieces and the stove vent, I painted bright white, since these original items, had all "yellowed"and gotten "soft" due to UV breakdown of the plastic. A very, very, sticky gray sealant was found on all mounting surfaces. "Gaska-A-Tape" I had on hand was used for re-installing. A bead of non-clouding, long life sealant will be used on upper edges before we leave for Alaska next summer as the 213 goes into heated storage today or tomorrow.
