    After my new deck/cabin top paint job I am in the process of re-bedding my portholes.

    Originally Westsail used Dolfinite to bed caprails, portholes. Even after all theses years it is still somewhat tacky & flexible.  The only place I've found to buy Dolfinite is Jamestown Distributors.

    Having worked so well for so long I'm sorely tempted to continue using it.

    My question is, might there be a more 'modern' bedding compound that is more preferable these days, something 'new & improved'?

    I used polysulphide to bed my portlights... my feeling was that dolphinite was more for a wood to wood bedding. Dunno if thats correct thinking but polysulphide has more of a "rubbery" texture

    I just removed two portlights that had been leaking for years, rebedded with 3M Marine sealant 4000 fast cure UV. Ask me in ten years if I'm happy with it.

    My next door neighbor in the slip next to me pointed me to this page.

    Lots of good info but the relevant part is 'rebedding deck hardware'.  He makes a case for staying away from 'marine sealants', especially 5200 ( which he calls 'devil glue' ).  Instead he uses butyl tape.  Pretty convincing.  And a learned a few new things about bedding deck hardware too.  Worth reading.
