Ok, finally i got a break from the weather. I used 220 grit and wet sanded it down to this:

A little closer

600grit wasnt doing nothing, so i used 220 and wetsanded. much faster process. although i passed factory paint to bare metal. It was a little hard to sand the edges. I still factory paint, some black paint and "sunburn" Before i start painting, do i have to sand to bare metal?because i think i got arthritis, lol( i sanded by hand, took less than an hour)
