T&T: ABC's of repainting aluminum?

[Keith]

I need to re-paint my boom and spreaders... the mast seems to be fine, just 
a little chalky. There is paint flaking off where I can see aluminum 
underneath... my guess is that they've been repainted before. I have no idea 
what to do, use, etc. Do I need to remove all the current paint? Methods? 
Primers and paint to repaint with? I want to DIY, so something brush applied 
or that can be sprayed without special equipment would be nice. Basic white 
for color. TIA.
