How to Choose a PPF Installer (and the Questions That Trip Up the Bad Ones)
Paint protection film is one of those jobs where the product matters less than the person applying it. Two shops can fit the same film and get completely different results, because the finish lives or dies on prep, environment and technique. Here is how to tell a good installer from a risky one.
1. Ask who actually lays the film
Plenty of shops are "authorised installers". Fewer can tell you the exact person who will cut and wrap your car, and how long they have been doing it. The honest answer should be a named installer with real years behind them. At Shoyi, Adam is an authorised trainer and installer for both SunTek and FEYNLAB — the team was trained by him, and every car that comes through is held to that standard.
2. Look at the environment
Film needs a clean, controlled, dust-free space. Any speck trapped under the film is there forever. If the work happens in an open driveway or a dusty corner, walk away. Ask to see where your car will actually be wrapped.
3. Ask about prep
A good installer will not put film straight onto dirty or uncorrected paint. The proper process is a hand wash, a clay to pull out bonded contaminants, then a cut and polish. Although PPF can cover swirls visually, skip this step and you are sealing in scratches and contamination permanently — the installation fails before the film does.
4. Understand the coverage options
There is a real difference between a precut kit and a hand-wrapped, edgeless finish. Precut is cost-effective and covers the high-impact areas. Hybrid and bulk installs wrap the edges by hand for an invisible film line. The installer should explain the trade-off honestly rather than quoting one number. An experienced installer will also point out what is possible with your specific vehicle — some panels suit one method better than the other — to get the best possible finish for the spend.
5. Check the film — and go deeper than the warranty
The film has a warranty. The install has no expiry. Asking which film they use and what warranty it carries is the right start, but it does not always give you the full picture. There are a lot of knock-offs on the market now, and some are sold under names that sound credible. Quality films are self-healing, hydrophobic, and engineered not to yellow. All films will yellow eventually — that is the honest truth — but cheaper films yellow significantly faster because of the raw materials and the glue chemistry. A good installer is selective about the film they use for exactly this reason. Ask how long they have been using that specific film. An installer who switched brands last month cannot stand behind a ten-year claim the way one who has used it for a decade can.
6. Watch for the upsell
The best installers tell you when you do not need something. Ceramic coating is a maintenance system, not paint protection, and a straight shop will say so. If everything is the biggest package every time, be cautious.
