I tried to use Meguiars Ultimate Pre-Wax Polish last weekend and applied it with my Megs G220 v2 DA. The polish left the paint really rough to the touch... I then used Megs Ultimate Wax atop this and it helped a bit but the paint still feels rough... I know now that this is because the Pre-Wax Polish most probably mixed with an existing wax on the surface and left micro particles that will not budge... So my question is what should I use to remove this roughness?? A few sites recommend a "cleaner wax" but in all my years I've never had to use one before... any thoughts appreciated.
