Cut your scotch-brite pad to fit a palm sander, conserve your elbow grease for important things like your favorite beverage afterwards.

The best results I've had with aluminum came from using Aluma-Prep, followed by Alodine coating before priming. If you don't need industrial quantities (expensive!), West Systems makes a small kit with both treatments in the kit. Use the prep first and rinse immediately; the water should run off in sheets. Follow with the orange alodine using a clean paper towel and rinse. Give it an hour to dry and harden, and prime. The alodine is orange so you can see where you missed with the prep.

Bob
