YES get the 3M adhesive added on. The rear hatch extras are a template I made, not a seadoo piece, but easy enough to fab up.
The website lists the size of the sheets. I don't remember what size they were, but I think 2 sheets was enough. I bought four for my current boat and only needed 3, so ended up with lots left over.
