cardboard mount glue

[P3D Gavin Stokes <gstokes@xxxxxxx>]

Hi all. I currently use cardboard mounts and have no plans to change.
However, I don't have a heat sealer nor any heat sealant.  What do you
people use to seal plain cardboard mounts?  In fact, I'd be interested in
hearing a brief summary of technique in general.  How do you position the
chips temporarily while adjusting spacing?

To seal, I've tried:

1. Rubber cement. Apply to many mounts at once, then position chips and
close mounts.  Eventually, they start to separate.

2. Glue stick. Didn't stick together, as I remember.

3. Spray adhesive. Laid out a bunch of mounts and sprayed them all.
Positioned chips and closed. WAY too sticky, and the frames where bordered
by bubbly nubbins of glue, clearly visible through the viewer.

4. Hot glue gun. Not too bad, but the glue cools so quickly that you can't
close the mount on it in time. Therefore, it doesn't press flat all the way
around, because some areas have already hardened.

In regard to heat sealing: How much heat is used, and for how long? How
close does it come to damaging the film? Can you use an iron? What's the
best place to get such mounts if I give up on plain cardboard? Do you think
I could make plain mounts into heat-seal mounts by pre-coating their
interiors with low-temperature hot-melt glue and then ironing them closed?

Thank you!

Gavin
