Thanks! That was beginning to be my suspicion. I have actually polished about half of the trailer so far, up to the final duo cycle part. So I will polish it. Since it was splotchy it fooled into thinking it was clear coat. This is on the top of the trailer, so it makes since that the clear coat should be about gone anyway.
