i did my split house windows using black butyl tape and countersunk oval head screws. Matched the black gasket mounted windows in the rest of the house.

Anyone have any experience with Lexan with Margard for windows. I used a lesser grade and they have not held up in the sun. (crows feet and clouding). Need a source also. Thanks

Just tried this product. Amazing results by hand. If I had a DA it would really be perfect. Front panes still need some more love, but I am completely satisfied. I believe I have plexiglass windows.

Lexan and windshield wipers will be a problem if you have or want wipers someday. It does react to detergents which may get on the windows when cleaning elsewhere on the boat. I looked at a Duffy to purchase. The windows not good.

According to some, that is not true. Apparently, wipers can be used on lexan with Margard. I am a convert. At first I thought glass was always the way to go, but listening to some with real world experience...I am willing to give it a try.

Genius is right, as mentioned in my post above. MarGard (scratch resistant) Lexan or other brands of scratch resistant polycarbonate will NOT be harmed by windshield wipers, washing with a brush or white Scotchbright pad. I have MarGard Lexan on both my boats windshields, both over 10 years old and clear as a bell. Never used any polish.
Don't believe me? By a small piece on eBay and try to scratch it.

My lexan is 8 years old and really starting to haze. I've tried everything to bring them back but no luck. I am debating on trying Margard, sounds like it would last a lot longer

I think you would be happy with the MarGard Lexan or equal.
BTW in your 3rd picture, it looks like a crack in the upper right hand corner, polycarbonate (Lexan) would never do that, are you sure that is what you used? It says Maxrolon on the paper which is polycarbonate so I guess you did. Is that a crack??

No, it's the reflection from my outrigger line but they did crack in several spots when I was tightening the bolts. Whatever brand my windshield is has held up incredibly well, maybe those are margard. I was going to put glass in next year but not sure yet

 

[Brooksie]

Yes, I would go with the genuine article LEXAN. Lexan can be bent in a metalworking brake without cracking (not the MarGard type) so I think your plastic, if cracked, is substandard compared to genuine Lexan. Holes must be well oversized to allow for expansion.

Is it possible to get a Lexan or Polycarbonate in a very dark tint?
I have not been able to locate a source if so.
I'm in the process of replacing my side windows all around and am about to move forward with just tempered dark glass. Frames are already in place and have sliding windows on both sides of my salon.

I would continue with the glass you have chosen. Lexan is available tinted but may not a direct replacement for glass sliders for several reasons.

Thanks for the input.

I'm no expert but I used lexan on two boats. One was an old 23 Tolman built in 2000 and the lexan lasted a long time. Maybe not as optically clear as good glass but lighter and I had no issues with scratching and they were bullet proof. One day towin gup to the highlands a cable truck was doing work and didn't block off the road and my skiff pilot house hit the cable and pulled it a bit until it snapped. no worries on the lexan

I installed mine with truss head SS fasteners and silicon. The main thing is to overvbore the screw hole for full thread and don't torque too hard putting them in, or you will get a little distorton you can see best with sun glasses on

I used lexan on my tolman 27 also but I tried to get fancy and do two sliders. where the windows pass each other they scratch all up. Because they are flimsy in the dual track. but for fixed windwos they work great. we use fresh water hosing them off ans sometimes a light mild soap to get summer bugs off from a 100 mile trailer trip I have a video of hitting them with a sledge hammer when I took the cabin off my tolman 23. the hammer bounced back at me.
