Scott Zinc is easy to find and rattle cans are fine . Go to NAPA and tell them you want the good stuff from the back . I am up to 3 cans on my boat and may need one more for the topside :D.you dont need a thick coat just a heavy dusting.

Re: zinc chromate .....

Be advised there are two types of zinc in paint.... chromate for aluminum and phosphate for galvanized steel.

Rustoleum sells a primer with zinc chromate in it but in only comes in gallon or larger.
