@ blockdoc, I appreciate the lack of flames because I opted to provide a devil's advocate perspective.
You can be sure I won't be flaming anyone for not having the same tastes as me in any kind of product.
the cost of the correction/coating will run you a good $900+.
I paid $450 for prep and application of OptiCoat Pro, done by a DuPont Registry Top 10 detailer.
Same price for my wife's Outback as my Raptor.
He may have given me a break, because we got OC on 2 vehicles plus Xpel on hers. But he didn't make it half price.
About DI water, I have a saltwater reef tank, and an RO/DI system that produces 75 gpd. My TDS is 1-2ppm. I could do a 2-bucket rinse less wash using it, but I just don't like that method. I'm opposed to anything advertised as "green".
