I'm getting used to polishing the Rv-7A. I bought a Nuvite system at Oshkosh this year and I'm really having a good time using it and the plane is starting to look great.
One thing I noticed today while using the C grade is on a pass with the unit, the cloudiness increased in a spot, and then I couldn't really get it out. It's not a huge deal, I'm just curious why this occurs?
