OGB has always been advertised as a durable and long lasting wax. Based on that claim, I purchased the product 2 years ago. I was somewhat disappointed in the durability factor based on claims made here. Patrick, I appreciate and agree with your realistic assessment of 4-6 weeks (max). I am not here to bash the wax. I've used some waxes in the past that have lasted maybe a week, two at tops, can we say Mequiars and Mothers? I recently went with the Collinite 885 fleetwax, and am pleased with its durability, but again, I do not believe the claims of some that it will last for 6 months at a time. I've used the Collinite on two personal vehicles, one garaged and one not. Obviously, the protection lasts a lot longer on the garaged vehicle. For winter, I estimated it lasting for 8 weeks worth of salt and semi-weekly coin-op soap and spray off on the garaged ride. I've reapplied it in April following a clay session and AIO cleaning, and now here we are in June, and it's holding up well on the garaged ride, and probably could use a reapplication in a couple more weeks on the outside ride. On both vehicles, the wax provides a nice shine. I've found that just hosing off the car with high power spray actually removes most of the surface dirt/dust, unlike other waxes that I've used. IMO, 885 is probably 40%50% longer lasting than the Blitz. Before I came to this site, I was using Nufinish, and honestly thought, and still do, that it does offer a level of cleaning and protection that is superior to a lot of the OTC 'cleaner wax' products out there. Today, I'm using the PC 7424, Klasse AIO, and Collinite 885, and am pleased with the results. I don't think that I would go back to the Blitz wax. Collinite's durability is that much better. Just an opinion.
