Wren: When i used it CG EZ G with Zaino it made it darker and metalics seemed to pop less then just Z on its own. IMO DWG has similar characteristics, Zaino straight up is my preference unless you like that overly dark, faux wetness that really cancels out the clarity and true colour of the paintwork.
wytstang: Nope no reduction in durability, if you want great looks then just polycharge your Wolfgang! RMG brings out way more metalic+pearl then DWG. Also, RMG keeps more in with improving, rather then seriously changing the optics of the paintwork :up.
RogueM3, Right now i would get the DWG :up
