Can you mirror polish an aluminum marine hull or will saltwater dull it?

A. You can electropolish aluminium and even buff polish it, but it will certainly go milky in saltwater. The chloride in the water will attack the aluminium and leave it looking pretty poor

Hi there,
We commonly polish aluminum boat hulls and then we coat them with Sharkhide Metal Protectant ⇨
Once you've done this, you can use the boat in both fresh and salt water for years without getting any streaks, stains or water lines.
