I can address that or at least my experience with Cheoy Lee
teak decks.

The original thickness of the teak overlay is only about 1/2"
and bedded and
screwed down to the glass deck. On my boat the screws were
machine screws
tapped into the glass and into the ply core.

Steve, we have a friend here that had the teak overlay problem
and fixed it by removing it, sealing the deck and then used
Treadmaster to replace it. I have the same on my Fisher and love
it, but it is hard on bare feet.
