This is less of a obvious goof on my part but still is a tale of rocket construction woes. Today, I went to apply a clear coat on some printed sheets that would become skins for my Odd'l Wedgie.
Can #2...sprayed for a couple of seconds then clogged. I tried to get it going but gave up.
Can #3...coated all three sheets. Took it back into the Dungeon and in spontaneously began spraying on its own. Pulled the cap and it kept on. I set it outside and let it empty itself. That is the first time I've had a spray can stick open much less appear to have stopped and then restart.
