When I do this (with a beige urethane-based construction adhesive) it does puff up a bit and can look rather awful. You can do exactly the same thing with epoxy, and the repair will look better, but I always seem to have lots of urethane glue around which I need to use quickly. (I assume the tape in the article uses an epoxy resin.) The expansion of the glue can be useful: for example, for reinforcing/repairing a cracked polycarbonate part recently, I drilled a few small holes in the polycarbonate on either side of the crack, then spread out the a glue-soaked cloth patch. When the glue dried it expanded up into the holes and swelled beyond, adhering the patch to the polycarbonate more securely.
