Skin is spectacular stuff. Nick it with a razor or scrape it on the sidewalk, and it heals itself quickly. Synthetic materials are another story, although it’s not for lack of effort on the part of scientists.
Chemists have tried for years to develop self-healing polymer coatings for use on cars, furniture and other objects. Recent efforts use microspheres containing bonding chemicals. These tiny capsules are embedded in the coating. When a crack or scratch occurs, the spheres break and the chemicals flow into the void, patching it.
Biswajit Ghosh and Marek W. Urban of the University of Southern Mississippi have come up with another approach, which they describe in a paper in Science. With their method, what breaks is not a sphere, but a ring-shaped chemical, oxetane, that is incorporated in the polyurethane polymer. Another compound in the polymer, chitosan, forms cross-links at the places where the oxetane breaks, healing the scratch...

“Hey, we can’t do this all day!”
I have never seen a more weaselly pitchman in my life. I can’t imagine anyone buying from this guy even if the product works. I can just imagine that most of his transactions start with “Pssst!! Buddy...!!”

Yeah, you have to wonder why a company would hire a stereotypical charlatan. Then again, the same folks who believe this clown surely must be Obamabots. He looks/acts like he would sell his grandmother for a substance that induces hyperactivity.
P.S. A product name with the word “sham” ought to be a red flag, like an investment guru named Madoff or a preacher named Dollar.
or a president named Hussein.
Or a restaurant called “Ma's” or a poker player named “Doc”...
