that stuff is alot like POR-15. it is used by the US Military to seal up the metal to keep from rusting. they did the testing at my base in japan because it is know as one of the toughest bases for climate caused rust. it used to cost alot less then POR-15 i dont know now but its good stuff. if you are going that far ever think about powder coating? i think it is really a better solution compared to paint.
