Ok.....I have tried and tried to find "self etching primer"for my new aluminum v hull project. I finally found some in spray cans at Oriellys Auto parts, but its 12.50 a can, and thats ridiculous!(The Oriellys around here are not "paint" stores like some are in the north.) I went to lowes and found this.......please tell me if you think this will work......it says on the back that it "contains acrylic resin and is a specially formulated base coat for aluminum. Provides a tight bond for the top coat, resisting blistering, flaking, or peeling.
