I just made my 1st purchase, and bought P21S Carnauba Wax, 303 Aerospace protectant, Sonax wheel Cleaner,303 Leather 3 in 1, microfiber towels. We have a NEW “machine grey” Mazda CX5 suv(3 weeks old) and I am worried about small rock chips on front and hood area since I have heard Mazda doesnt use a lot of coats(paint chips easier). Would you recommend putting 2-3 coats of a sealant on first, then coats of wax over that! Taking a road trip to Gatlinburg in 2 weeks! I also have a good Meguirs paste wax, and spray wax at home. Would appreciate ANY advice you can give to protect my grey SUV, I have ruled out clear plastic paint protection, like 3M, since I am leasing, and dont want to invest hundreds of dollars, and ruled out leather car bra, since I read debris or dirt caught under neath can scratch!—THANKS, RICK
