I have heard of that. Anyway, I made my decision: - I will treat the aluminum parts with alodine and nothing more, - I will use a black self etching primer on my steel parts (WAFs mainly). I have no idea what that primer is, but I bought the can once upon a time in South Africa, and I know it works bloody well.
Alodine seems to me the cheapest, easiest and safest way to make an undercoat on aluminum parts. By the way, I bought the alodine, and I realized it was the wrong one. There are two types: 1201 alodine is transparent, 1202 alodine leaves a gold finish.
