Painting Aluminum?

my dad runs the USPS body shop in Chicago, i had asked him before about painting an aluminum john boat, he had said there is a special primer to use for the paint to stick.
 
It is a peice of 1/4" aluminum diamond tread that I'm using to make a set of 1/2 doors for the /forums/images/graemlins/k5.gif.

like he said above, there's a primer to put on it to help make it stick.
 
alodine.
i dont know if a non comercial place can get it. its a corrosion preventative deal as well. you have to clean to a water break free surface. then you apply the alodine as per directions that im not going to go into as with different brands they varry a bit. then a light coat of non zink chromate primer, you can get it in spray cans or two part, then you LIGHTLY sand the primer and hit it again, then you paint it. now, this is for aircraft methods, so maybe automotive methods are different.

I think Eastwood has a primer for Aluminum. I have seen it done before.
