I think DG should revamp there packaging and labeling if they want to compete. In the retail market It looks a little bit 1980s. Unfortunately, most non detailers probably would buy a Surf City product, apposed to a DG product, as the packaging is more "gimmicky" and modern. Also, I think they should consider classifying their products more in line with other manufactures.
It seems like they call almost every LSP a "polish". Polish to me means something to correct defects. It's says nothing of the great protection the products are known for. I think of they called it something like: Duragloss 1 step: Cleans, Polishes, and Protects, they would sell a lot more retail LSP or AIO style products. Maybe consider calling their sealant only product, just that a "sealant". The numbers mean nothing to your average Saturday car washer at NAPA. Maybe that is not the market they are going after, don't know.
