Well I've been cleaning the E320 as often as I can so it's been easy to keep on top of, still very pleased in how it shines up though. The car has simply been hand polished with some Autoglym Super Resin Polish and then coated with two layers of Collinte 845. Today the car was pre-washed with Valet Pro Citrus Pre-wash, cleaned with the usual two buckets, Dodo Juice Born to be Mild and then vinished off with some Gyeon Wetcoat to add even more beading niceness!! Wheels also receieved a coat of Chemical Guys Wheels Guard for good measure. Gave the engine a little clean up as well, comes up nicely for an engine bay with 103k on it.
