Matte wraps, PPF and ceramic coatings: when the correct answer is 'do not polish'
Paint protection film (PPF) and ceramic coatings each change the plan in their own way. Quality PPF has a self-healing top layer that swirls lightly and then recovers with heat, which the summer sun here provides for free; light machine polishing of PPF is possible but uses different products and a gentler touch, and edges must be avoided so the film does not lift. Ceramic-coated cars present the opposite problem: the coating is a sacrificial glass-like layer sitting on top of the clear coat, and polishing removes it entirely. If a coated car has picked up marring, the honest conversation is whether to decontaminate and top up the coating, or to polish off the old coating and reapply — a bigger job that should be quoted as one.
The operational takeaway is simple: surface type determines process. Before booking, state plainly whether the car is factory gloss, resprayed, wrapped, filmed or coated. A vendor who does not ask about any of this before quoting a polish is quoting blind.
