Other than the aviation zinc chromate / phosphate "rattle can" primers, what hardware store "rattle can" primers work well on bare aluminum ???

1-Whats the aluminum alloy?
2-Whats the environment?
3-Whats the topcoat?

There are plenty of self etching rattle can primers that will stick to aluminum. SEM makes one, as do a few others. The compromise many of those make is they have no sacrificial elements, so offer little in terms of additional corrosion protection.
