The first thirty days
Film and coating both keep curing after you drive away. What you do in the first month decides how the next five years look.
First 7 days — leave it alone
Adhesive is still wetting out. No washing, no pressure at the edges, no polish. Small water pockets under fresh film are normal and clear on their own.
Days 7–30 — hand wash only
Two buckets, pH-neutral shampoo, clean mitt. Keep the lance away from film edges and panel gaps.
No automatic washes, ever
Brush washes put swirls into paint and can lift a film edge. This is the single fastest way to undo the work.
Wheels get their own bucket
Never acid cleaner on hot rims. Coated wheels release brake dust with a plain rinse.
Deal with contamination fast
Bird droppings, tree sap and fuel splash etch even coated paint if baked in. Rinse and remove the same day.
