My 1998 Sabre was a pure white bottom. I did the job myself. My advise is over do the fill, get it raised up a good bit and wet sand it down slowly. I started off with 600grit just to knock the rough area of new gel off and then moved up to 1000 grit. Finished off with 2000 grit, to polishing compund and it polished up real nice. Really was not that hard, other than getting up the nerve to take sandpaper to the boat!Here is the before and after linkhttp://basscatowners.yuku.com/topic/28419#.Vx__FEfE8bAClint
