[Public-List] Paint hull liner & deck #560

[Mike Lehman]

John,

I agree completely with using silicon and would not use it anywhere except 
for the windows. I used GE Clear 35 year silicon...the secret is to tighten 
the screws 'almost tight'; let the silicon set for 24 hours and then 
complete the tightening of the screws thereby forming a gasket for the 
frames. I did this 30 years ago and never had a leak. I re-did the windows a 
few years ago, not because they were leaking, but because the glass became 
crazed and I switched out to 1/4" instead of 3/16", lightly-tinted, 
Plexiglas.

Very interesting on the use/recommendation of silicon.

I am near the end-stage of completely rebuilding one side of my cabin
trunk due to the utter and complete failure of silicon sealant on the
portlights (and every other single place on the boat that stuff was
used) put in by a previous owner.  We took the frames off to rebed them,
and the whole side of the cabin trunk delaminated in my hand.

A few hours with a grinder to get back to good glass, some marine ply
epoxied into place with glass cloth and mat built up around the fillets
and I am getting close to final glassing and fairing.

I'll not use silicon anywhere on my boat, and a number of old boat
restoration enthusiasts agree:

As always, your boat, your choices, and your mileage may vary...sealing
portlights is one of the recommended uses, but given my experience?  No
thanks.

Fair Winds,
