Painting aluminum siding
Done right it should not peel for decades. Some here have good luck with a proper prep job and a GOOD exterior paint but everything I have ever learned suggests using Emulsabond in your first coat of paint.
I would power wash, scrape and if necessary scrub with a stiff bristle brush to get down to a sound surface. You will still have some chalking left but get as much of it as you can off before you paint.
Latex Primer: Good for Drywall, that's about it.
Behr Paint: The plastic buckets are good, that's about it.
