My mother would never let me play with acid. I can't figure out why.
I do know it took some pretty rough stuff to shine up the potmetal bezels for my head and taillights. They were extremely dull and powdery looking, but they were relatively straight, so Jim and I decided to give them a lye bath. A BOILING lye bath.
First, we had to gather certain supplies...a very large stainless steel pot, a burner for frying turkeys (borrowed from a friend), large, black chemical gloves, and finally some Red Devil lye.
