Home Depot, Lowes, Ace all should have it. Buy a throw away paint brush apply to both boat and rubber piece and let it sit for about 15/20 minutes then stick them together. Make sure your glass is clean of any wax. I would clean area with acetone to make sure it's clean. If you buy the small contact cement it comes with an applicator on the lid.
