Follow up ONR with
FK 146 (anti static cleaning detailer) to clear away
water spots or any soil that might not have come off with ONR. After a quick pass with the 146 spray the car is shiny enough to leave as is.
Both ONR and 146 leave the surface slick and really make me wonder why I ever bothered with a hose and a foamy bucket of wash soap.
Then I do a quick application of Aqua Wax topped a few minutes later with FK 146 for aditional dust repelling and suuuuuper slickness.
Dirty water spots never really "stick" to the paint anymore. They just melt away with the next ONR session.
