Works well, but only time will tell how long it will prevent oxidation from causing it to fail. I used this to prime the aluminum frame on my screen porch. Some of the posts are 5 inch square aluminum posts, and after time, the aluminum oxidized and cause the paint to buckle and peel off. The section I used this on as a test was the post next to a door. I used a sanding disk on my orbital sander, and removed all oxidation from the metal. It has to be shiny, and without any discoloration. Then wipe the metal clean with denatured alcohol, let it dry by wiping it dry with a paper towel, then wait a short time and prime the metal. I used a foam brush to get a really smooth finish. Wait for it to dry so you can lightly sand it before the final coat of paint.
It has been over a month of rain and the metal still looks like new, only time will tell how long the repair will last. I have a lot more aluminum on the porch to fix. The most important detail in my work is about getting the metal clean and free of all oxidation. If you leave any amout, no matter how small, it will grow and cause the paint to buckle and peel.
