My wooden shop is very old and is eaten by insects. The door away from the door next door is closed with a very small door. Two of them were badly rotten. Water leakage is bad, and the two doors are corroded. So, I fixed the door. To display my treasure, the other was a mirror. The worm-eat part was covered with a film of organic solvent. Old materials sometimes bother the manufacturer, but it is a lot of fun.
