4Runner Sunroof Glass

Autoglass are hard to break, they are laminated with this special
coating so they wont shatter. You really dont need that much
visibility on a sunroof unlike the windshield or other windows. Did
you try testing if that thing will leak from a car wash?
if you need a bandaid fix while the glass is not yet available then
try Silicone RTV to cover the cracks. Use a rubber squeegee to flaten
em out. You may need to put something hard underneath so that glass
wont weaken when youre pressing on it. BTW, Use the clear and not the
gray stuff.
