I have to agree with BcBouy, waste of time on daily drivers. I've been detailing cars since the 70's. Have seen almost everything out there, within reason. Rusty Jones, PolyGlyCoat, now Ceramic coatings. I've tried two different products, one from Meguiars, the other TEC582. All require a wash, paint clean (buff) then their product application. Bottom line, is it the buffing, paint cleaning that gives the 'slick' feel after all said and done, or is it the ceramic application? Hard to say, but subsequent washes and most airborne dirt will wash right off. Heavier debris on paint will require a thorough wash and away goes your ceramic coating. For show vehicles, yes, for daily drives I would lean to...'no'...and stick with a normal vehicle wash/wax routine. Just my opinion
