That's what I like about using the backing plates. While thay are a bit bulkier (about 1.24" on the round and 4mm thick), they do provide a very big sealing surface and, apparently, the use of a wide range of sealing methods.

Thanks all. I think I have a number of viable options now.

: You have such a large piece of wood that you could probaby use any
: household caulking compound. There are a lot of inexpensive
: acrylic /latex /urethane based caulking compounds. Run a bead
: around the weebing and when you pull it up the caulk will squish
: a bit between the inside of the deck and the wood base of your
: padeye. Once it hardens it will be a fine sealant and a weak
: adhesive. With the decklines in place you don't need any
: adhesive at all to hold the padeyes in place, so the strength of
: the adhesive is irrelevant. Inexpensive caulk will keep out
: water just fine. When it comes time to replace the padeyes or
: the webbing, a sharp tap will dislodge the caulk, and it can be
: cleaned up by gentle sanding.
