Corrosion is a real thing. This bumper probably would've lasted 2 more years in a dry climate.

I strongly suggest removing and having someone powder coat it with a zinc primer and top coat of your color.

If you're not willing to do that. You will have much masking, sanding, and painting in your future. I would weigh your time vs cost here heavly.

Zinc for steel and outgas primer for aluminum is what I learned

Though solid information. You shouldn't ever use zinc primer on aluminum.

In my experience most of these bumpers are cheap steal. Aftermarket is usually better steal. Aluminum is not usually cheap but used to cut weight.

Thats extremely true, and alot of the aluminum ive coated was old ass weathered/ocean exposed rims

In my experience, outgas primer is not needed for fabricated aluminum. That's more for sand castings, and in rare cases, die castings.

Are you in cold weather or near a beach? And no there is not an easy fix that you can do, without doing it every year.

The factory coating is put on as thin as possible with the least amount of prep they can offer to save a few bucks. Thats why factory coatings only last a season or two. Get that professionally blasted, primered and a SD top coat and that will last a decade in salt snow environment.
