I covered everything; this stuff is messy. Spray each side & wait 5 min. It's supposed to be sun resistant. Once I start, I have plenty of time to work w/ it.
I'm not sure I recommend this spray type adhesive anymore. It used to be amber and thicker resembling super weatherstripping adhesive, now it's clear and doesn't bond like it once did. Someone mentioned Dap. I may try it next time.
