Brian, I got a pair of replacement cut plexiglass pieces from Bob at Montgomery Boats for a reasonable price. He pointed out that I would have to drill the holes to fit my particular fastener pattern. They arrived with the contact paper still on them. I haven't installed them yet, so haven't decided how to seal them. My deadlights have no beauty trim, and are currently siliconed in. And in a couple of spots they leak (both are cracked, one is chipped at a fastener point). Does anyone have a recommendation for sealing the replacements? David (M17 #393 Cloud Girl)
