How to Spot a Bad PPF or Ceramic Coating Installation
Investing in Paint Protection Film or Ceramic Coating is the best way to preserve your vehicle. But a bad installation can leave your car looking worse than before it was protected.
Knowing how to audit the work before you leave the shop is crucial. In this guide, we reveal the specific defects that separate a master installer from a "speed shop" apprentice.
Signs of a Bad PPF Installation in Calgary
PPF is clear, which means it hides nothing. Poor workmanship usually manifests in 4 key ways.
1. Visible Bubbles & Air Pockets
There is a difference between water bubbles (tiny moisture spots that dry out in a week) and air pockets (white voids that will never disappear).
2. Misaligned or Exposed Edges
Premium installations wrap the edges. Budget installs stop 1/8th inch from the edge.
| Feature | Budget Install (Bad) | Premium Install (Good) |
|---|---|---|
| Corner Coverage | Exposed corners collecting dirt | Fully wrapped corners |
| Edge Gap | Large visible gap (1/4") | Zero gap or wrapped |
| Relief Cuts | Visible "V" cuts on curves | Seamless forming |
| Alignment | Crooked lines | Follows body lines perfectly |
3. Contamination (Dust & Hair)
A clean room is mandatory. If you see specs of dust, lint, or even hair trapped under the film, it means the shop environment was dirty. These specks create "tents" where the film doesn't stick, eventually leading to failure.
4. Razor Cuts (The Nightmare Scenario)
Inexperienced installers cut on the car. If you drag your fingernail across the edge of the film and catch a groove in the paint, your paint has been sliced. This requires a repaint to fix.
Signs of Bad Ceramic Coating in Calgary
High Spots (Shadows)
Darker, rainbow-like patches on the paint. This happens when the installer forgets to level the coating. It looks like an oily smear that won't wipe off.
Hazing / Cloudiness
If the paint looks duller than before, the coating may have been applied in high humidity or wiped with a dirty towel.

How to Audit Your Calgary PPF Install
Before you sign off on the work, perform this simple 3-step check:
- 1
The Flashlight Test
Use your phone's light to scan the edges. Look for lifted film or dust specs.
- 2
The Sun Inspection
Pull the car into direct sunlight. Check for holograms or "high spots" in the ceramic coating.
- 3
The Edge Check
Open the hood and doors. Are the edges wrapped around? Or do you see a visible line where dirt will collect?
