How is a bulk install different from a pre-cut one?
The difference is where the film gets its shape. In a bulk install, the panel itself is the template; in a pre-cut install, a plotter cuts each piece to a stored vehicle pattern before it goes anywhere near the car.
| Step | Bulk install | Pre-cut install |
|---|---|---|
| Film off the roll | Oversized sheet | Cut on a plotter to the car’s pattern |
| On the panel | Stretched and anchored, then trimmed | Positioned and squeegeed |
| Final shape | Set by a knife on the car | Set by the pattern |
Film makers support both. 3M’s PPF installation guidelines talk about cutting film “for bulk parts or plotter cutting”, describe a bulk hood install in which the film is pulled out to all four corners and anchored there, and list a cutting knife with 30-degree blades among the tools. SunTek says on its PPF FAQ that its installers have pattern-cutting software that trims film to the contours of thousands of makes and models.
What are the trade-offs of trimming on the car?
Flexibility on one side, a blade near the paint on the other. Trimming in place can cover a part no pattern exists for, but every cut is made on the car, right next to clear coat, rubber seals and trim.
3M’s colour change instructions, written for vinyl, make the risk plain: film at panel seams has to be cut carefully, “being careful to avoid scratching the paint.” Patterns move that cutting to the plotter, and SunTek’s cutting software adds editing tools so installers can adjust a pattern, including shortcuts for badges and sensors, before the film is cut. Fine knife lines in paint or trim are among the warning signs covered in judging a PPF install.
Why it matters when comparing PPF quotes in BC
Two quotes for the same panels can describe different methods, and the method changes what you should check afterwards. Ask each shop whether film is plotter-cut or trimmed on the car, where its edges will end, and whether any relief cuts are planned. What a PPF quote should include has the full checklist, and the PPF buyer’s guide for BC drivers covers the rest of the decision.
How Brookswood Tint cuts its film
By computer, from a template for your particular model, so the outline is fixed before any film meets the paint. The shop’s PPF page puts it as no blades on paint. LLumar Platinum then goes on with edges wrapped wherever the panel allows, as described under wrapped edges.
Partial Front starts from $850 and Full Front from $1,550; every package is listed on paint protection film. The tint side of the shop works the same way, explained under plotter-cut tint.
