Oh, so your exterior screws were just wood screws screwed into the cabin trunk? Is there coring there? (I'm hoping not). I'm skeptical of Don Casey's theory that bolts or screws were used in surface mount installations just to hold the pane in place while the sealant cures. If they just needed something to hold it in place, one would think a big clamp would've done the trick. Maybe it's simply a change in theory/opinion on window security, or perhaps VHB didn't exist in the early 80's. Here are a few pics of what I have: https://drive.google.com/open?id=0BxfHpwssU_6NcU92OHFhU1p6b00 Since I have thru-bolts, and no other LF38s seem to have them, my theory has been that a prior owner installed them because the boat was being prepared to go offshore. But maybe C&C did it and the screws vs thrubolts was just a factory difference or a change they made over the years. -Patrick > On Tue, May 23, 2017 at 9:26 AM, Paul E <dre...@gmail.com> wrote: > >> Patrick, >> >> I didn’t have any thru-bolts, just exterior screws with finish washers. >> I did fill in all imperfections with expo/thickened epoxy.
