Wax or sealant: fine for a car you lease
A sealant after a proper wash and clay (part of our Full Exterior) is cheap protection for a season. It wears off, so it has to be repeated.
Ceramic coating: for gloss and easy winter washes
A coating bonds to the paint and outlasts wax by a wide margin. Salt brine and slush rinse off more easily, which matters in a Massachusetts winter. It does not stop chips. And it locks in whatever is under it, so the paint must be corrected first. See Ceramic Pro coating.
PPF: for highway commuters and cars you keep
If you drive Route 128, the Pike or Route 2 every day, the front of your car is being sand-blasted. Film is the only one of the three that physically absorbs that. Most people protect the high-impact areas (bumper, hood, mirrors) instead of the whole car. See paint protection film.
What we usually recommend
- Leased car, 2–3 years: sealant with a Full Exterior, maybe coating if you hate washing.
- New car you plan to keep: front-end PPF plus coating on the rest.
- Older car with dull paint: paint correction first, then decide.
