When i got my series on e the paint work was as flat as fook.
One of my mates suggested mopping the car.
Was a little bit hesitant as heard some horror stories, but OMFG what i difference looks like its just been painted.
But one thing i did find out speak to supplier etc is you can use 3M rossa hand glaze as a normal polish used it last weekend and is by far the best polish i have ever used.
Easy to apply and a joy to get off can even be used on the glass and plastics.
Its a little on the pricey side but very good.
