I just bought a '78 50V just like that on Wed! Love it.
I was at the Por-15 web site the other day for fun - looks like great stuff! (Just don't let a bead of sweat drop in the paint can. If you do, throw it away. Wow.)
Did you do the 3-step process or jsut use the Por-15? How did you get it to coat the entire inside of the tank? How did you drain off the excess? What did you use to plug the petcock hole while doing this?
5 day drying time? As you can tell I'm kind of curious about the process. I know muriatic acid will clean out rust but it looks like por-15 keeps it from ever reappearing for life.
Come on up for the Ghost ride on Monday - I'll have my red one there.
