On my 1999 Bavaria 35E, there's teak decking on the cockpit seating. In a couple of areas, it is lifting at the outer margins. The worst being against the forward coaming where it curves toward the companionway area. I've tried three different adhesives and even used concrete blocks for weight, but it continues to lift. This is very hard to access. I certainly can't get under it to clean out whatever layers of adhesive are there (between what I've done a couple of tries and the previous owner's work). I'm tempted to use a couple of short stainless screws countersunk just so it grabs to the FRP below. I can probably cover the screws with teak bungs. I'll use some bedding material and hopefully keep the screws at a minimum length so I don't create any water intrusion under them. Bad idea to use screws and just get this done with?
