Product Details
Moeller Zinc Primer Aerosol Spray works great on aluminum surfaces above or below the waterline. This power primer etches into the aluminum, forming a strong surface/primer union that is resistant to corrosion. Choose the color that contrasts least with the topcoat you intend to apply over the primer.
For steel and iron surfaces, especially welded joints, above or below the waterline, use Zinc Cold Galvanizing or Zinc Phosphate. This corrosive barrier contains a high percentage (95%) of zinc, for maximum resistance against solvents & abrasions.
Available in a 12 oz aerosol spray can.

Q: null Can this zinc primer also be used on aluminum marine engine heads (does the paint have some heat tolerance)?
7 years ago1 Answer
A: Sorry, I have no idea, I think you would have to ask the manufacturer. If the heads are under a shroud so not exposed to salt water, I would look for a high heat primer used on automobile engines, likely available from an auto parts supply.

Q: null I need to topcoat the zinc chromate primer with an epoxy primer. Are they compatable? The primers are being applied to a 4130steel tubing aircraft fuselage frame.

A: Bob, I bought the primer for exactly the same reason you did; 4130 chrome molly tube welded fuselage. I just used the zinc chromate primer as the only primer and sprayed an enamel on top of it. 2 years later (and still not flying!) the paint job looks good. I also used the ZC primer for the aluminum parts where I thought primer was called for. disclaimer: I am no expert on anything, just working through trying to build an airplane.

A: I USED THE ZINC CHROMATE PRIMER ON ALUMINUM OUTDRIVE THAT HAD LOWER UNIT PAINT WORN OFF AND REQUIRED PAINTING. I FIRST USED WEST SYSTEMS ALUMINUM ETCHING (TWO PART) AND USED CHROMATE PRIMER FOLLOWED BY OMC COLOR TOP COAT( MOELLER). FINISHED PRODUCT LOOKS GREAT AND HAS, SO FAR, SHOWN NO ISSUES. SINCE TOP COAT WAS ONE PART PAINT, I WOULD WAIT A WEEK, OR SO, TO ALLOW COMPLETE DRYING BEFORE IMMERSION AND/OR WATER FRICTION AS BOAT CAN DEVELOP AT HIGHER SPEEDS. HAPPY WITH RESULTS.
