Now what? Vinyl top install

Good ideas, thanks.

Edit.
So I contacted DAP like Super-Cuda suggested (not sure why I didn't think about doing that, panic I guess)

They said I can add another thin layer of adhesive on top to re-stick the surfaces together, even if it has been days.

The "2 hour Open Time" is how long you have to stick the surfaces together before the adhesive is too dry to the point where you would need another layer of fresh adhesive

With that said, I guess I will follow his advice and give it another shot.

Wish me luck.
