So, I wetsanded many times before. But, this time, I just don't know what went wrong. I was working on a 2003 Corvette gas door. Had a small scratch in the clear, so I did my usual and wetsanded it out. Went over with some M205 then on to the 365 sealer. Car looked great.
I ran into the car again like a month later. Did a once over and noticed that the spot in which was wetsanded was extremely dull like I had never even polished it at all.
What could have went wrong????
