I was patching up a jig saw puzzle that used to be a door pocket that had been bumped with a foot/leg too many times. JB weld was spread over the cracks on the inside, packing tape on the outside. I then laid bamboo skewers in the areas that were marinating in JB weld, including under the top ridge and the three hoizontal spaces between the raised lines of plastic that i assume were there to help structural integrity. The next day I reinstalled the panel and when I exited my leg hit the panel and it flexed but did not break. PBS had a show on the other evening about the making of samuri swords and having a soft metal core that the harder, more brittle, steel is wrapped around to assist in avoiding breakage. So my adhd brain took that idea and now I have samurai door panels that are much more forgiving than before. JB weld and bamboo skewers clearly is a match made in heaven.
