Well, I have good news. If you don't like to read long winded stories, I can simply say that I got 99% of the white paint off. I will post pics later on when the sun comes up and I'm done with my junk tour around town.
One night, while fooling around in my father's garage, I got paint drops on his beloved 1956 Thunderbird. In a panic, I called my friend and explained that I was in a bad spot and needed these paint drops off the car. My buddy was in an automotive program in our high school, which in my mind made him a pro.
My buddy arrived and I showed him the damage. In true Jeff Spicoli fashion, he said, "I can fix it."
He laid out his tools, which included a thicker than usual razor blade, a can of rubbing compound and a can of carnuba wax. He said that if you tip a razor too far one way or the other and the job will be ruined, but at just the right angle, magic will happen. Thirty minutes later, the paint drops were gone and the car looked perfect again.
Fast forward MANY years, and his technique was used here with great success. Aside from a very few spots where the paint actually blended with the original paint, I was able to remove the white drops.
EDIT:
Here are a few pics of the merchandiser along with its new living quarters. They're only original once and at this point, I'm more than satisfied with the end result. I have plenty of tools to hunt and of course the near impossible to find topper sign but as you know, I will keep searching until I can search no more.
