...Feel better now?
Folks, this is a message board. Opinions are going to differ, and people are going to be staunch in their beliefs. The insinuation that one must own stock in their water company for supporting a traditional wash as a safer means of washing is silly. No one is disputing whether or not ONR works, the question at hand is the risk of marring that ONR poses vs a traditional wash. If you ask me, there is a higher risk. Does that mean that ONR might not be able to handle it? Nope. Does that mean that I'd rather err on the side of caution with a customer's vehicle? You bet your ass it does.
I believe ONR is great for mild to moderately contaminated vehicles, I do not believe it is the ultimate solution to exterior car care. Have fun rinseless washing baked on mud that adheres even after a pressure wash. Actually, that'd be a good test and put an end to the debate. Take a freshly corrected truck, go mudding, let it sit on there for a week, and then wash one half of the car in ONR, and the other half traditionally. Only problem would be finding someone willing to correct a car just for it to go mudding and prove a point... Which is why it's probably never going to happen, and in-tun, is why we all learn to accept other's views without getting upset and resorting to petty remarks.
