I finally have digested all of the great info from you oldgassers regarding restoring origianl porcelain signs. I have procured all of the equipment and supplies so tomorrow I am going to start on my guinea pig sign, an ATLANTIC WHITE FLASH sign that's approx 4' X 2' in size, red white and blue. I dug through my container and picked this as the lucky contender.

I'll roll the dice and see how it comes out. I will take a before and after picture to post.

THANKS for all of the good help!
