Looking for best choice for products for painting alum cockpit fab
stuff for salt water use.

The item is top- about 6' x 8' double sided so about 100 sq ft so not
a lot of materials - but looking for long term, no maintenance finish.

No finish is not an option. Anodizing may be but don't know about
availability for the size.

Thinking some 2 part paint (Awlgrip?) - with what prep, primer ?
