The Zinc Chromate primer comes in a spray can and can be found in theaircraft parts suppliers like Wicks, Aircraft Spruce & Supply, etc. It's achoice primer because it isn't effected by the MEK based covering systems(i.e. Stits). Some people plan to use latex house paint to fill and finishtheir covering rather than the MEK stuff but you still have to glue theDacron fabric down. Traditionally this means using the MEK based adhesive.All of the MEK based stuff dissolves the primers you are talking about, andyou end up with a gooey mess. So unless there is an adhesive that iscompatible with acrylic-enamel paints and primers, you probably are betteroff getting some Zinc Chromate.Robert Haines> I notice all aircraft metal fittings have this pretty green paint. Thehardware store had primer, but only in versions of brown. Guess I willspray the brackets with brown. But where do you get the green paint? Isthat a standard spray can?>> The green paint is probably Zinc Chromate. It is a primer for alum parts,> not necessary for steel parts.>________________________________________________________________________________Subject: Pietenpol-List: Lycoming for sale
