Before spending money on PPF or ceramic coating, check these 7 things on your paint first. A working installer's honest pre-purchase checklist.
Most people decide on paint protection film about five minutes after signing the purchase agreement. The car smells new, the paint looks flawless under the dealership lights, and the last thing anyone wants to hear is "you might want to slow down." We get it. But there is a version of this story where someone drops real money on a full front PPF install, then we pull the car under the lights and find existing damage that either needs to come out first or is now sealed underneath a film that will last a decade. That version of the story is expensive and avoidable.
This is the pre-purchase checklist we actually walk through before quoting any protection package. Whether the car is brand new off the lot, a CPO pulled from Carmax in Roswell, or a lightly used two-year-old lease return someone found on Facebook Marketplace, the same seven checks apply.
Check the paint surface under real light first
Dealership showrooms are built to make paint look good. Specifically, they are lit to hide every swirl mark, water spot, and buffer trail that exists on that car. Step one is to look at the paint in direct sunlight, or under a focused inspection light if you are indoors. Run your eye across the panels at a low angle. What you are looking for is any marring in the clear coat — the kind of surface damage that comes from automated car washes, improper drying, and years of enthusiastic but careless detailing. If the paint needs paint correction before PPF or ceramic coating, that work needs to happen first. Film over uncorrected paint is just a very expensive way to permanently preserve damage.
Check for orange peel and texture inconsistencies
Factory paint is not perfectly smooth. Every manufacturer ships cars with some degree of orange peel — that dimpled texture that looks like the skin of, well, an orange. Some brands run smoother than others, and some panels on the same car will have heavier texture than others (door skins are often worse than hoods). This matters for PPF because the film conforms to whatever surface is underneath it. Customers who want a glass-smooth finish after the install need to understand that PPF does not fix orange peel — it follows it. If texture reduction is part of the goal, that conversation needs to happen before the quote.
Look for pre-existing rock chips and road rash
GA-400 does not discriminate. New car, used car, babied weekend driver — if the front bumper, hood, and mirrors have seen any highway miles, there is a reasonable chance they have already taken some damage. Rock chips don't care how much the car cost, and they have a head start on you the moment that car leaves the lot. Small chips can sometimes be addressed during the PPF prep process, but deep chips that have broken through to primer or metal need proper touch-up before film goes over them. Sealing moisture into a chip is how rust gets started underneath a film that looks fine on the surface for the first two years.
