Aluminum boat paint

[Bread Man 1]

I need your help guys. I am going to paint a small Jon Boat of mine, and wanted to use Duralux paint. I can't find any dealers in this area. (at least listed online)
Duralux makes a paint specifically for aluminum boats. I painted another boat of mine with some old military paint I found at a surplus store several years ago. It lasted about 10 years. I went that route, but can't locate any of that paint either. It was probably a one shot deal. Once it was gone, it was gone. Anyone have any suggestions on another brand or type of paint based on their experience?
