What can I use to glue the flashing to the glass?
I think I'd start with rubber cement and see how it goes. If it doesn't work Gorilla Glue or your favorite other polyurethane glue.
I tried the rubber cement. It didn't last
Unless it's tempered glass, it's easy to drill holes with a diamond glass bit. My wife does glass art and I've drilled many holes for her. Just go slow and have someone keep it wet with a squirt bottle. I suggest using bolts with rubber washers.If it's tempered glass, don't even try. You'll break it for sure.
Even if it wasn't,I'd still probably break it .Wife's truck, that would not be good.
Thanks guys. Looks like the Locktite Super Gel,, Marine Adhesive ,or Channel Bonding. One should work,. Appreciate the help
