HELP with bodywork

On the sanding, I like rough in all the little spots of mud with a cheese grater (remud the cheese greater marks) then 80, sand the entire car with 80 DA (to feather all edges) and then give it a quick block with (spray style) guide coat, also in 80. Then I prime it, (2coats) guide coat with the rub on style and block it all with 180 then prime again (more rub on guide coat) then 180 then prime (you guessed it more rub on guide coat) then if it needs it 180 again and prime then prime again (more rub on guide coat) and wet 600. I am using k38, though with a fizz can I think you have the right idea. Good luck and leats see some pics. Also you might want a self etching primer for the metal spots.
