Tip
TAPE the glass with duct tape first. Big X then horizontal mid height. Really helps to avoid disasters. Leather palm or nitrile gloves. Small ball pien hammer. Crack window on top of tape. Large trash can. Safety glasses.
Polycarbonate note. When the Kelley II was built .750" house windows. Extra cost anti scratch coating. Apply pure carnauba wax no polish pure wax.
I think the issue with Quicksilver was DOT federal standards call for 1/2" glass for school buses. Don't know why but softening sharp corners and edges on glass reduces stress cracking. Go figure.
