usually not recommended unless you spray zinc chromate first. Most of the newer primers are Ok on aluminum.

 

Epoxy is the way to go on Aluminum.

VR&C.

 

If you want it to stick.... Prep it first. Typically some sort of trivalent or hex chrome dip/ spray is required. Zinc phosphate also works.

But for those of us on a budget. Check out the link below, it'll be worth your time

Aircraft Spruce has quite a few aluminum primers - works on planes, fine for cars.

 

I've had good results the last 10 years using Valspar Direct to Metal two part primer . Covers well with great adhesion , sands nice and doesn't shrink back after time . As a plus you can get it tinted to match what ever topcoat color that you're using .

 

Lacquer primer will not work. Please provide information about the aluminum. Is it anodized? Do you plan on sanding or just degreasing and topcoating? Do you want the aluminum in a primer? Or a actual topcoat? These questions need to be asked before ANY recommendations are given.
Aluminum is a easier metal for paint to stick to because it's softer, however it can corrode very quick. Lacquer primer doesn't bring anything really to the table, it will only provide a mechanical adhesion (by sanding).
