Those flip ups are spicy. How well do they seal when shut?
As @Fj81 said no leaks. In most cases more water proof than the factory slider. We now use a double bubble seal that per our instructions is so tight when first installed the panel does bow and needs a couple weeks of warm weather for the bubble seals to compress and the panel flatten out. Our Gullwing windows have logged more trouble free miles and been seen in more countries than any other window.
The Gullwings on my 80 series are still the original hand cut prototypes. They dont leak and the final CNC production design fit is better.
