Many people ask me about the grey primer on my 55 when i had it at Pigeon Forge last week. I have since looked up the guy that did it for the guy i bought the car from several years ago. He said it is nasson K2 primer sealer. I had already ask the previous owner and he could not remember, so i went straight to the source when i got back in town. I have some pictures of the car stripped to bare metal and when it still had the neptune green and ivory paint on it wide white wall tires and all. I will post them sometime if anyone would like to see the transformation.
