The new design looks good. When you cut your new windows use lexan
not acrylic.

I need to find out what lexan is - I suspect it might be a US brand name for
something else. Polycarbonate?


Yes it's a GE product

LEXAN resin is the world's foremost engineering thermoplastic. One of
the toughest and most versatile polymers, its unique combination of
features is used to add high quality and high performance to thousands
of products.

The LEXAN brand is also a strong signal of quality that can help
consumers recognize products that enhance the way we live, work and
play.

When I first started restoring RedCloud I used Acrylic. One night
when it got very cold the steel on the boat did not shrink as fast as
the acrylic, it sounded like someone walked around the boat with a 20
pound sledge hammer as each and every window gave way under the
strain. With the lexan someone could walk around the boat with a 20
pound sledge and smack the windows and the hammer will just bounce
off. I used 1/4 inch dark lexan. Be fore warned they will need
polishing every few years to keep them clear.


When you put your new windows on oversize them slightly and do like
the car mfg's do and paint the back of the lexan black around the
edges to cover the sealant.

Ah, good point - I was already planning to darken the areas that don't have
the actual window aperture behind them - if the sealant is light in colour,
I'll need to disguise that as well. :-)

Yes darken any areas behind the lexan and use the masking effect of
painting the back of the lexan to hide the sealent even if it is clear
sealent you will like the neat look much better. Looks factory done.
