I wash my daily driver (White Knuckle Dodge Charger) about once a week to keep clean and put a layer of Meg's UW on it about once a month. I'm just about finished with my gallon of Hyper Wash and considering switching it up. I've been pretty pleased with the Meg's so far - it's inexpensive, foams great in the cannon, and leaves a nice finish that dries easy but it's not the best cleaning product I've ever seen. I'm considering switching to DG901/902 as that seems to be very popular with it's cleaning ability and shine plus price is close to Hyper Wash (in gallon, not broken down per wash). Some have commented about the additives in DG being great and some don't like it. My car is white so adding gloss or warming up the color is difficult in the first place but I'm thinking about grabbing a gallon to try. For a daily driver maintenance wash will DG be a good switch? Anyone that has used both have a good opinion or review?
