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, all our permanent in-house staff are trained by the best, every one with years of experience behind them.
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. Skip this and you are sealing in swirls and marks permanently, and the installation fails before the film fails.
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.
5. Check the film and the warranty
Ask which film they use and what warranty it carries. Quality films are self-healing, hydrophobic, and engineered not to yellow. Cheaper films still go yellow over time, which comes down to the raw materials and the glues. A good installer is selective about the film for exactly this reason. Ask how long they have been using the film, too, to back up the claim.
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.
