Why are you using ONR if the car is clean?
What constitutes "great" durability? Is the lack of "great" durability your only barometer for being disappointed with it?
Excellent, especially for the money. However, I wish that it didn't streak as easily as it does.
Their leather protectant? I love it too, it's currently my favorite.
I think that Optimum receives a lot of attention because: 1) The vast majority of detailers at various forums are very satisfied with most of their products 2) Their prices are very reasonable in light of the quality that you are getting.
I don't think that anyone would dispute that, in general, "there are just as good if not better products out there".
The question is whether there is a single company that *consistently* releases as many quality products for such reasonable prices as Optimum. The answer to that question, in my opinion, is probably not, but if there is, it would be limited to just a couple of companies.
