Building a Sea Chest

[mbmcdermott18]

The chest and bilge are painted and I have the chest partially assembled. I hope to put everything back in the bilge and install the sea chest this weekend.

I am wondering what to use for sealing the many threaded connections when plumbing the chest. In two areas I have to orient the fittings a certain way so they may not be dogged down as tight as possible. I am looking for a compound that will be strong enough to keep a tight seal.

I have asked a few folks and got different opinions from pipe dope teflon tape marine sealant etc. I was thinking of using 4200 so it would be strong enough to hold everything together but I would still have the ability to disassemble everything if need be.

Any ideas on what would be the best product for this application?

I will post a few pictures this weekend. I have been bad about remembering to take pictures as I go along.
