Micro-marring is usually the fear of many when they hear about ONR, however shampoo washes daily mar car finishes. Each time I see a black car drive by with wash induced swirls and marrings i shake my head and wonder why many careless about their car. Inevitable friction generated by human and environmental contact with automobile finishes causes scratches, swirls and marrings. However, wash is by far more culpable than any other factor. Bucket filled with shampoo will not solve the problem, when folks take dirty wash mitt in dirty shampoo bucket to their car finish...when individuals scrub automobile paint as though it was porous. I believe the chief goal of car wash is to remove loose grim that comes from exposure to the environment. After this is done, more specialized cleaning can be done to remove tar, grease, rail dust e.t.c ONR cleans as good as any car shampoo, however lt requires right technique and tools. For my method, I spray down each panel with a mixture of ONR and distilled water wipe in one direction with zero pressure so that premium grade microfiber can do its job without being bugged down. Then I flip the towel, spray down second time and apply low pressure to pick up fine dirt still left behind. My last spray down is with Quick detailer made with Optimum No Rinse, I sray sparingly and buff dry with shorter nap side of wayne's microfiber towel. One whole side of a mid-size car will take me five minutes. The whole wash process without tires 20 minutes. One directional wipe with ZERO pressure on first wipe and low pressure on second wipe will virtually eliminate swirls and significantly reduce marring. I've been using this product on Ferrari, Aston Martin and other delicate finishes with great success. During rain for additional lubricity I spray down panels with FK425 diluted with distilled water 60/40 before ONR spray.
