If the dealer Superguarded the paint with swirl marks already in it, all it would have done is seal them in, another reason why I declined it being done on mine. If these Permagaurd people de swirl the car first then apply it that will be something worthwhile.
The other thing to bear in mind seeing the state of paint when it comes from Renault on my car, just from the new car prep, I would have hated to see how many more swirls they put in when applying the superguard.
