Hi Support-gangers,

I am looking forward to the arrival of an extra mangled keyboard that
Ian Daniher is going to send me.  When it arrives, I intend to try
several different types of glue and methods of gluing to determine what
would be the best for simple "field repairs."

When (and if) I get it "perfected," I will post it on the wiki with all
sorts of caveats and disclaimers (eg "proceed at your own risk).  I
would like it to be something folks who didn't want to wait for a new
keyboard could do as a temporary fix, and that schools where the XO is
be deployed to be able to do the same.

Some of the glues and sealers would be quite costly if it was used only
for one keyboard, but I suspect it will be "a little dab'll do ya" (like
the old Brylcreme ad).  Schools could keep a tube or jar on hand and do
many repairs.  Maybe local repair centers would stock it, or maybe folks
would have other uses for the substance.

Here are four of the glues and sealers that seem to be the most
promising. They range from aquarium sealer to a veterinary wound sealer
(I will ask a local vet for a little bit to try).  Could you folks check
these and give me any input you may have based on experience with them?
Also, if you can add to my list of possibilities, please do!

Glue Ideas:

Zap-A-Dap-A-Goo is an all-purpose adhesive and sealant. Not a super
glue. Bonds virtually anything to anything. Gooey, strong, clear and
remains flexible. For porous and non-porous surfaces. 3 oz. tube. 3 oz
for $5.69

3M™ Vetbond™ Tissue Adhesive (n-butyl cyanoacrylate) provides quality
wound management. It polymerizes in seconds after contact with tissue
and body fluids and binds wound edges together so natural healing can
occur. 3ml for $14.99.

Weld On #16
Fast Setting. Syrupy in consistency. Skins over fast but slower setting.
Will leave a mess if spilled.
Acrylic to Acrylic. Polycarbonate to Polycarbonate. ABS to Acrylic.
Multi-purpose. Good for sealing tiny gaps and water-proofing small tanks.

Silicone Rubber Adhesive/Sealant meets the following requirements:
FDA: FDA regulation No. 21 CFR 177.2600 when fully cured and washed.
UL: Recognized for service to 302°F (150°C) where elongation is not
necessary.
3 Ounce Tube) $4.15

Cheers!
