Welcome to Optimum - there's years of experience on this forum! ONR will not effect any coatings hydrophobic properties. Dilution ratios for ONR = 1 oz to 2 gallons normal wash, 2 oz to 1 gallon clay lube, 8 oz to 1 gallon for ;pre-spray/instant detailer, and 10 oz to 1 gallon for waterless wash. My dilution ratio for Power Clean (unofficial) = 100% PC for engines/heavy duty cleaning, 3 to 1 PC for bugs/tar/wheels, 5 to 1 for interior (and some even go 10 to 1). Opticoat products are tweaked to use on Coated cars - No Rinse is slicker with more gloss than traditional ONR, M Wash has greater cleaning properties, Tire Gel is not different (because you don't Coat tires). We don't test products on competitor Coatings but Opticoat No Rinse won't affect any Coatings performance.
