"sealers" from the dealership? When I bought my acura tl, they wanted to charge me $450. I said let me see it, and we'll go from there. Same stuff from Ohio Auto Supply that I had in the garage, around $30/bottle that did about 8 cars. New car protection, how I do it. Dealer doesn't touch it, i drive it home dirty inside and out. Wash with a stronger soap that will remove oils, old wax, etc.(don't use this but 1x or 2x a year), paint prep(isopropyl alchohol or similiar), Clay(Griots has a 200+ gram bar for around $30 does several cars), sealer over everything windows, chrome, etc(not trim), rain-x glass over sealer, seal door edges, under hood, etc, wait the 8hrs for sealer to cure(Blackfire Wet Diamond is my current go to sealer), carnuba over all the paint. Just my 2 pennies...and i use a machine with the lightest pad possible, and some by hand.
