FYI: When you have a crackly window, don’t slam your doors! A hole may appear and chunks of glass might / will fall all over the place. The fix you ask? Everyone has seen it, but don’t make a rookie mistake and use Duct Tape that will mess up your paint and might pull the paint off! Use painters tape and it looks coooooool!
I just loved this pictures and had to post them. You can also check out the Naval Safety Center web site for more stuff.
