Hey Darryl, thought you might like the little SB off-shoot. The blue is Septone Metallic Blue (Hammer Finish) bought in a simple spray can from Super Cheap Auto. It's slightly darker (and a lot brighter) than the original blue but still true to the original look of the mower. I've also found removing all traces of paint with warm caustic soda and then sealing the bare metal immediately with paint oil provides an excellent base for the paint to stick to.
Cheers,
Craig
