So, I decided to do a test area for the POR15 Metal Mask today. The nice new steering box we installed back on page one wasn't looking so new anymore. It was starting to rust on the surface and I always did regret not painting it before we installed it. So, it was the prime candidate. We scuffed it with scotchbrite and then washed it down with acetone. Two coats of POR15 later and, presto!!!
