Well, today we are going to put the epoxy primer on the sanded and prepped parts. The first picture is the hand made aluminum gas tank. The 2 holes are where the relocated oil tank fillers stick through. Most paints don’t stick well to bare aluminum so it is important that you clean and etch it with a mild acid solution. The PPG DPLF epoxy primer is great for painting aluminum like this tank and also for sealing fiberglass parts like the fairings and tail. Since these parts had previously been painted, putting on a coat or epoxy primer is a good way to avoid any bleed through from the old paint. The final quality will only be as good as the prep work, so doing this right is critical.
