Cleaned Pan

I am done cleaning the pan. I figure I ground and sanded down all the rust I could without grinding through the metal, and I painted it with some rust eliminating black primer. I am going to cover it all with new heat and sound insulation anyway so what is the point of making it perfect and I think its basically there anyway. But you tell me. Notice the rust on the passenger side. The driver side had already been worker on in this picture.
