Anna's calf-high Bogs have been leaking for a little
while now.
I cut out a small piece of
inner tube and tried to seal it over the troubled area with a product
called Seam Grip. It's
clamped down and needs to dry over night.
It took over half the tube to
do the left boot, so I used a cheaper adhesive called Welder on the right side which cost a
fraction of the 18 dollar retail price of Seam Grip.
It looks like seam-grip is a urathane based thermosetting resin.
Generally urethane based adhesives bond very well. If the formulation is flexible enough it should last a while. Using a piece of rubber to bond on is a very good idea. When bonding a so-called single strap joint is much stronger than a butt joint.
Try not to get this glue on your hands, though. Urethane adhesives usually contain isocyanates (mostly MDI). These are known irritants to the eyes and skin. Wash with lots of water and soap after skin contact.
Good experiment! BTW, keep the remainder of the tube of seam grip in your freezer. Not sure why that is, but I believe that's what it says on the back of the package.
Looking forward to hearing how the two adhesives compare...
