Re: Hardware Store PVC Sheets as Deck Hardware Material

Starboard is a lousy backing plate material. It moves under load.

Best to use fiberglass epoxied to the underside of the deck.

Re: Bedding stanchions

In my opinion the best solution is backing plates made of fiberglass offcuts or G10 epoxied to the deck.

Re: Bedding stanchions

Rubber pads should not be used - never should have really. Butyl or another good bedding compound is the best choice. When hardware moves, and stanchions move more than most hardware, the sealant should stretch and follow, maintaining a seal. Rubber pads just let water in.

That means the butyl was already cured. It's an elastomer, so the properties vary depending on how much cross-linking occurs.
