I sandblasted the whole bottom of my '51 ford over the winter of 1987-1988 (with the suspension removed) and painted it with POR-15. It looks as good today as it did them. This was a out-state Minnesota car with some rust, but nothing serious. The issue with POR-15 is that UV light is hard on it. Since the area I did has never been exposed to sunlight, it has held up very well.
You didn't have to get everything scrupulously clean, just get all of the loose stuff off. I realize this is not a recommended restoration technique, but I didn't know any better then and it has held up well.
