It makes sense but I would have to practice a bit on scrap before I tried it on the real windows. Al S.V.

If you carefully polish and buff the edges completely smooth, cracks don't have a way to start themselves.

Stock car racers use polycarbonate for windshields in their short track race cars. It is the more crack and impact resistant of the two plastics, but more likely to cloud if you are too aggressive washing it. It is a trade off like everything else, but I would lean toward the Lexan in that application. Both of my boats have long Plexiglass side windows, and both have one side that is cracked vertically more or less in the middle.

These cracks are leaking. I cannot recall if I used polycarbonate or cast acrylic. Of the 2 choices which would be the better for replacement? They are relatively long windows that are held in only by the Sikka Flex. This time I plan to use 3 M tape.
