I've used the DG line for a while also. IMO, they are highly underrated products that can be found locally. Polishes (silicone polymers) seem pretty durable, lasting several months, and are easy to use. I would say the polishes are more durable than many of the boutique sealants used on this forum. Wash solution is one of the best out there, IMO, as it cleans well and leaves a nice gloss. Leather cleaner and condiditoner are great too.
I am highly impressed with the new AquaWax. I think it is far and away better than OCW. I persoanlly do not think OCW is providing much paint protection after a decent trial. Others may think differently, but I just was not impressed. The AW beads longer, is slicker, and looks great! I've noticed my car stays cleaner much longer with the AW than it did with OCW as well.
I think DG are great products. I used Zaino for many years and if it wasn't available any longer, DG would be my choice. In fact, I alternate using the products anyhow.
