Re: Bedding Deck Hardware With Butyl Tape
The butyl should be between the handrail and the deck, with a countersink on the cabin top where the fastener exits the cabin top and enters the handrail. Never use sealant - butyl or other types - on the inside of the boat. All that does is guarantee that any leak will enter the core and you won't know it. If a leak does develop you want to know it asap.
