Re: what to use on unpolished paint ?
as an x professional paint sprayer, if it's been repainted and it has dust particles in the surface you need to deal with it using some professional equipment and products
3m ultra fine da sanding discs to remove the dirt inclusions, sand it matt flatt
3m trizact discs then this removes the scratches and ensures that when when you polish it you end up with a mirror finish,
G3 by farecla is brilliant used with an electric buffing machine
3m finishing glaze with a matching mop head is certainly the product to remove swirls etc
Then loads of TLC and a good body wax regularly, oh sorry lets get back to the car!!!
there is a good few hours work to do the whole car dut it's worth it when you are done.
