so freaking bored want to shoot myself?
You should use 60 or eighty on the rust whether it is fairly within the metal,a hundred should do for the paint.And if the rust just isn't unhealthyUse like a 320 to feather the edges where the metal meets the paint 320 must delicate out the metallic from the eighty grit paper and feather the restThen use a 600 or 800 before the primer, after is all painted use 2000 grit moist sanding to get a shine againUse sharpening compound then swirl remover then a wax after you use the 2000 gritThat is alot of labor to do
