If you are looking to keep the boat long time and in good looking shape. The current window frams will be a
never ending project. The things will have to be sanded and primed and painted year after year. Once the corrosion
starts its hard to control.If you have blinds,curtons or some sort of treatment inside the boat it will help deflect heat.
However purchasing the tented glass is the way to go. There are many kinds of glass it is a personal choice. Putting a film on the outside will help but will peal or scratch in time. I have replaced all the windows and frames using Cape Lookout windows Brodas Rose.

The rear window frame and glass from Cape lookout windows was around 3,500 ths side windows both sides meaning 4 pieces of glass and frames was about 9,000. It is a little costly but you are through with it no more sand and paint. I elected to jell coat my frames black,
i am done. The front windows were glassed in when the boat was new. This is the only pick i have but if you would like to see more and closer let me know i will get some this weekend and shoot them to you.
I AM FAT IN THE PICK BUT I HAVE LOST ALMOST 60 POUNDS ITS A LIFE CHANGER. But now i can crawl around in the engine room. HURAY
