So get tinting with PolyFilm.
- Pre-clean vehicle window glass thoroughly
- NOTE: for rear windscreen remove the brake light, speakers and parcel shelf if needed prior to cleaning.
- Thoroughly clean both sides of the window with a soapy water solution.
- Be sure to wipe away all dirt and grime from the surfaces.
- DO NOT use household cleaners or ammonia based cleaners.
- Use a lint free cloth to completely dry the surface prior to applying the film.
- NOTE: The clear backing liner (covering the adhesive) of the film is slick and the tint film side is slightly tacky.
- Trim film to a rough size using the exterior of rear window as template
- Unroll the window film identifying the backing liner from the tint film side.
- Spray the outside of the back window lightly with soap solution and lay the film on the outside of the rear windscreen with the clear backing side facing you.
- Using a sharp safety knife, trim the the film first (leaving the additional border of 10mm-25mm or 1" inch) and pull any excess window film away slowly as you go.
- To trim the top of the vehicle back window, use the natural curve as a guide, also leaving the additional border to be trimmed for fit later.
- NOTE: Be careful not to cut or damage the vehicle while trimming the film.
- Remove the Backing Liner while the film is still on the exterior of window
- Carefully remove the backing liner of the film while still in place on the outside of the side window.
- TIP: To avoid damaging the film edge place a piece of adhesive tape on both the backing liner side and the tint side to help peel off the backing liner.
- Lightly spray the now exposed adhesive side of the film. You should also wet your fingers to prevent leaving fingerprints during handling.
- You can use the removed backing liner film inside the vehicle to prevent carpet fibers getting on the adhesive side of the film.
- Handle carefully to avoid creasing, crimping or getting dirt on to the exposed adhesive.
- Spray both the inside of the rear windscreen and the adhesive side of the film one more time with the soapy solution.
- Applying the film and final trimming
- Now to apply to the inside rear windscreen surface, remove the film from the exterior holding it from the top at either side then slide yourself into the vehicle.
- Once inside position the film at the top of the interior rear windscreen and move downwards working the film onto the glass.
- To hold the film in place, squeegee an area in the middle.
- Stretch out the film by hand by pushing outwards from the middle so that it fits into all corners and edges.
- Then, holding the film stretched out, squeegee to finally stick down firm. Do this in sections, first the middle section on each side and then the tips and corners.
- Trim to fit inside rear windscreen glass as accurately as possible.
- Firmly squeegee the window film in place always working from the center out. Take care to push all air bubbles towards the nearest edge. This will also allow you to push any excess soapy solution from the surface of the film to the edge so it can be wiped away with the lint free cloth.
