I did it myself and it was quite easy. I assume that these are
external seal tape, not internal seals.

The previous post mentioned sanding with 220. I didn't and wouldn't.
In my book
gelcoat and sandpaper should stay far, far, apart. The seals have
stuck for
3 years now with zero problems.

Having a friend help get things on straight is useful.

John,

Your choice not to sand. However, if you check with some of the adhesive
mfgs(3M has good info on their site), you'll find that sanding is
recommended for optimal results with acrylic adhesive as are used to stick
down Mylar. Light sanding of the surfaces to be bonded is the way to go as
it provides the adhesive with more bonding surface and mechanical "bite".

As JJ noted, it's also important to have the surfaces squeaky clean, use
pressure (roller), and only apply tape to warm surfaces for best results.
Also position controls to keep pressure off the Mylars for a few hours as
acrylic gains strength over the first 24 or so.
