Re: [Amel Yacht Owners] Sealant for dodger windows?

I never do any silicone work anymore without these

They make every job a pleasure and leave a professional clean job that can be prone to make you feel smug.

Pat and Ian, that might be a workable idea, but it would be a lot of work.  Getting the masking tape right to paint the edges (to cover the sealant) was a huge job, and this would be the same again.

James, both of your ideas seem like much less work.  I had not considered using longer screws.  That still leaves the problem of getting the butyl tape into position, and it's very frustrating to cut... so I think perhaps I'll go the silicone route.  I also was not aware silicone could be easily wiped off acrylic.  I thought I would have to use a solvent (like acetone) which would attack it.  I'm surprised mineral spirits is safe; I usually consider that harsher than acetone.

Does anyone have a recommendation for a silicone?

   If you want to use the butyl tape, just get some longer screws, pins or even some drill bits that fit the holes in your window panels.  Next locate a few corner holes in your frame.  Insert two long screws pins or whatever you are using into the matching holes in your new plexiglass and hold the new panel an inch or two above your window frame.  You can now work the long screws or pins into the holes you exposed in the frame and at that point lower the plexiglass into perfect position on the first try.  From that point just install several of your permanent screws and remove the temporary long locating screws or pins.  If you still have concerns, do a dry run without the butyl.  You will need some extra hands.  And no worries cleaning most silicones off of acrylic.  You can pretty much remove it with a clean rag.  Mineral spirits or paint thinner is safe for the acrylic if needed.  Don't use anything harsh like acetone.  I will let someone else recommend the sealant.  I will be using the Dow Corning 3145 Gray on mine.

Hi all,

I'm replacing my dodger windows. I've had the acrylic fabricated, I've painted the edges, I've filled and drilled the screw holes... The only thing I'm missing is the sealant.

I had intended to use butyl tape, but the stuff I got is way too stickly to work with. It's almost impossible to cut, and even if I got it in place, I'd be unable to fine tune the window position before screwing.

I think the original sealant was a type of silicone. Does anyone know what it was and how it was applied? I'm scared it will squish out onto the window and I won't be able to get it off the acrylic.
