A common misconception is that aluminum is immune to corrosion. While aluminum cannot rust, it can still fall victim to galvanic corrosion, pitting, and crevice corrosion. Vehicles near the sea or where road salt is heavily used are at a higher risk. If your aluminum parts are showing signs of corrosion, an excellent way to bring them back to life is to have them sandblasted and then powdercoated. This will seal the surface and give your parts a fresh look.
