: Can anyone describe in (idiot-level details) what the process of applying
: HH-66 and then activating it?

Below is a link to various PVC items glued with HH-66 and a heat gun.

sections of this link)

Mask off the areas to be glued. Lightly wipe down with MEK in one direction.
A paper towel work fine if you don't wipe until the paper sticks. Allow to
dry completely as moisture is a byproduct of using MEK, and moisture will
inhibit glue adhesion. Use a heat gun "lightly" to speed up this process.

Carefully brush on an even coat of HH-66 with a throw away 1" brush. Move
quickly but don't slop it on.... maintining a wet edge, and don't overbrush.

Let it dry to the point that the two sections to be glued don't adhere when
they come into contact. 30 minutes should be enough. If you see
any areas you missed, add a thin second coat to the entire glue area and
allow to dry. A heat gun can speed up drying, but use very little heat as you
don't want the cement to boil.

Allow the HH-66 to dry , and then overlay the two halves of the float bag
being sure they don't stick. Masking tape everything in place ( blue works
best) on the work table.

Once everything is in place, Use your heat gun to reactivate the HH-66.
Carefully heat small sections ( 12" or so) while pressing down firmly with
the palm of your hand, ( wear a glove), or better yet, use a small hard
surface roller. Keep the heat gun moving, and several inches away from the
surface to prevent burning the PVC. You want it to be hot to the touch in
order to reactivate the HH-66. Go over the entire surface with heat and
pressure a second time.... less heat than the first time.

Wait a few minutes after gluing before removing the making tape. If the tape
is hard to remove, heat it a little while pulling it off slowly. This
takes much less heat than used for gluing.

Allow the bag to sit overnight before inflating.

Take your time, be careful, and the results will reflect this.
