Paint protection film (PPF) goes on wet, like window tint, but it's thicker and stretchier, and every panel is a different shape. Whether you're doing it yourself or checking a shop's work, here's how a good install is done.
1. Prepare the paint
- Wash and decontaminate with a clay bar or iron remover to take off bonded grime.
- Correct the paint if needed. Film locks in whatever is underneath, including swirls and chips.
- Wipe with isopropyl alcohol to remove wax and oils so the adhesive can bond.
2. Cut the film
- Pre-cut kits are cut on a plotter from vehicle-specific patterns. They're the easiest route and there's no blade on the paint.
- Bulk film is laid on the panel and trimmed by hand, which lets the installer wrap edges fully, but takes skill and a very light blade.
3. Apply with slip and tack solutions
- Spray the panel and the adhesive side with slip solution (water with a few drops of baby shampoo) so the film can be moved into place.
- Position the film and anchor it in the center with a squeegee.
- Use tack solution (water with a little isopropyl alcohol) on edges and curves to help the adhesive grab.
- Squeegee from the center out, stretching gently into curves. Overstretching thins the film and leaves marks.
- Wrap the edges around panel edges where possible, so the film edge is hidden and less likely to lift.
4. Cure
- Small water bubbles and haze are normal and dry out over one to two weeks.
- Don't wash the car for about a week, and avoid pressure-washing film edges.
- Warmth speeds curing. Heat helps light scratches self-heal once cured.

DIY or professional?
Small, flat areas like door edges, door-handle cups and headlights are good first DIY projects. Bumpers and full hoods are much harder to do without wrinkles. For large areas, a certified installer is usually worth it, and it's often required for the film's warranty.
