I would personally recommend Silpruf. My understanding is that it was designed to put windows in skyscrapers and it has 100% elasticity. When we put windows in the SC 50's, the rig shop I worked for was the only one I am aware of that would guarantee the window installation. I would recommend black for the color. Takes more to cleanup but looks better overall IMO (Looks like a shadow line vs dingy white after a number of years).

The key is to have some space like Brendan mentioned. I use small nylon washers on either side of the bolt holes to maintain the gap vs E-tape.

The key is to only tighten the window so that it is snug (less is more in this situation) and not to over-tighten. Oversized holes in the windows is key as well like Brendan mentioned. Once everything has cured, you can tighten the bolts a bit more but only tighten the barrel nut on the inside. You want to take care not break the seal on the outside. You likely won't need to do this but if you do, then that is how I would do it.

If you do the job, I would highly recommend you do new windows as well. It is a big job and you wouldn't want to make the effort without new windows IMO. It would probably take me 6-10 hours for the 4 windows in the Express to do it right and I did a lot of windows back in the day when I worked as a rigger.

SC 50 was 8 hours per 8ft window for reference. That is a pull, prep and seal new windows in.

:: I don't use acetone on the windows but have not observed

:: Next time, I may try what I've seen on Yeti, a foam

:: blue tape the window edges before a race or use Stay
:: Afloat puddy (smells like jerky) if surface is dry or
:: wet. Jam into joints or cracks.

:: :: :: Generally windows leak through the screw holes, though

:: :: :: The cabin top flexes a lot when walked on and will break

:: :: ::
:: :: :: To re-bed the windows they must be removed, all old
:: :: :: sealant carefully cleaned from boat and windows
:: :: :: (difficult as you should avoid using acetone or solvents
:: :: :: to clean the boat or windows), and then resealed. It may

:: :: :: drilling through lexan without a proper drill will cause
:: :: :: micro cracks that spread later. Note that Tap will bevel
:: :: :: and/or melt edges to your specifications for a very nice

:: :: ::
:: :: :: After breaking several windows during races, I switched
:: :: :: to polycarbonate windows, which scratch more easily but
:: :: :: are much much stronger.
:: :: ::
:: :: :: When re-bedding windows, you want to have a good

:: :: :: to cut tiny squares of white electrical tape and placing
:: :: :: them near (1/4" away from) the screw holes, so when you
:: :: :: fasten the window in place there is still a thickness of
:: :: :: silicone to make the seal. Don't tighten the screws
:: :: :: until the silicone has set up somewhat, and then don't
:: :: :: tighten them very much. Remember, you want a thickness
:: :: :: of silicone to make the seal.
:: :: ::
:: :: :: Masking over everywhere that silicone should not go
:: :: :: (window, cabin top) is a good idea, as silicone that
:: :: :: gets loose will both make a mess and make future
:: :: :: painting / repair jobs go poorly.
