I'll use whatever the advice here is. There just has to be something that works, even if it has to be replaced every x months.

Boatlife makes Sillycone and polysulfide (Life-Calk) and a combo (LifeSeal)

It use to be fun when they were down the street as i use to repiar there tube filling machines and stock-up


My boats PO used most everything and the only downside i have seen so far is you REALLY cant get the Sillycone OFF to the point of lifting gel coat BUT it did NOT leak

All sealants have their proper and/or preferred uses, and silicone has a number of such on boats...usually where flexibility, removeability and thickness are important criteria. FWIW what comes to my memory are the OEM instructions for Beckson opening ports and replacement lens for several hatches ( see DIY-BOAT.COM - Hatch Lens Replacement 4/20/01) which specified to use only silicone as sealants.

Certified...in several regards...

You are dealing with massive damage from small leaks that rot interior wood

Bene,

If you eventually plan to replace the deadlight just use silicone to seal it up as best you can. If the surfaces are clean I imagine it will stay there for a year. You are sealing between the plexy and the aluminim frame correct?

I sail.

If your issue is that the lens in a hatch is leaking, then you should just remove and rebed the lens...using only silicone, unless the OEM has a different specific recommendation. It's a simple job, the work is mostly removing the old sealant from the lens and the alu frame. Get those clean, and resetting the lens is a piece of cake, and it will last for many years. Smearing a coat on top may not be successful, and is not likely to look too good.

And if you take the time to do it right immediately, you won't spend all the time trying to fix it later, or fix the damage from the leaks the half-assed approach will leave you to deal with.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

What is the best way to remove the lens, using a flat razor blade from underneath or what?

Yes the lens is leaking. I ought to try taking it apart and rebedding it. Not sure there's a downside since I'll have to get it professionally done anyway, if I do nothing or if I screw it up.

Either way, I REALLY want to stop the leaks.

Yeah, leaks REALLY REALLY SUCK! My boat has a seemingly endless supply, so I feel your pain

My guess is that you'll find fixing this one of the easier jobs on a boat.
