Review on 🔥 Rust-Oleum 8781502 Stops Rust Flat Aluminum Primer - High-Quality 32 Fl Oz Can for Ultimate Protection by Kino Gerami

Works well but only time will tell how long it will prevent oxidation failure. I used this to prime the aluminum frame on my screen porch. Some bars are aluminum 5" square bar, and over time the aluminum will oxidize causing the paint to warp and peel. The section I used this on as a test was the jamb next to the door. I used a grinding wheel on my orbital sander and removed all oxidation from the metal. It should be shiny with no discoloration. Then wipe the metal with denatured alcohol, let it dry by wiping dry with a paper towel, then wait a bit and prime the metal. I used a foam brush to get a really smooth finish. Wait for it to dry so you can sand it lightly before the final coat. It has rained for over a month and the metal still looks new, only time will tell how long the repair lasts. I have a lot more aluminum to fix on the porch. The most important detail in my work is the cleaning of the metal from oxidation. If you leave a piece, no matter how small, it will grow and cause the paint to blister and peel.
