Had a chat with my mate who works at a bodyshop the other night about this.
I think this is what he suggested:
1. Rub down and clean up, remove all grease and dirt
2. Key up with wet and dry
3. Etching primer, a couple of coats
4. Rub down smooth with fine wet and dry
5. Normal primer, a couple of coats
6. (as 4)
7. Paint. Can be whatever you want but gloss will give shiny finish, a few coats

From there you can rub down again with rubbing compound and give another coat, then a coat of lacquer, rub down, and polish/wax for protected finish.

600 from primer.

then go to 800, 1000 after doing each coats of gloss.

dilute the last coat with cellulose to go on top of flatted 1000; it shouldn't need cutting down.

To cut down on the amount of prepping onto ali. I'd be inclined to use Barcoat. My local paint supplier recommended it - as used by off-roaders on their Landies.
A couple of top-coats - job done.
Cheers, Pewe

Barcoat is only for use on top of existing paint to stop new paint reacting, it is not a primer, if sprayed directly onto ally it will peel, as will non etch primers.

You must abrade and use an acid etch primer for a lasting result.

Oh yes! Def go for acid etch. Anything else will peel off pretty quickly and start looking horrible!!! Nasty stuff though so wear a mask!! I didn't and the wind changed and I almost choked to death!!!

1, Key up the ally with 240
2, Apply 1 light then 2 medium coats of high build etch, Glasurit do a nice one. Hand block with 400
3, Apply 2 coats of polyester black basecoat
4, Apply 1 light then 2 medium 1k clearcoat

Don't use any wet and dry, water is the last thing you want anywhere near the car paintwork. The primer is designed to chemically combine with with the next liquid that it comes into contact with - that is better to be your colour coat and not the contents of a rubby bucket





If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
