gas tank restoration

I am finally getting around to posting the pictures of my gas tank back from restoration. I took it to a Gas Tank Renu place south of Indianapolis. I am glad to have it back and in good shape but it wasn't quite what I was expecting. I thought it would be some kind of powder coating process but it is a thick tar like substance baked on. It just doesn't look as clean but it is a gas tank after all. The first two are before pics of the outside and the inside. The last two are obviously after pics. What you can't see in the before picture are the many small pin holes in the bottom. Carl
