When applying paint protection film (PPF), slip solution is essential to place and move the film without it sticking permanently to the surface. However, simply squeegeeing out the slip solution may cause the film to still slide out of place due to the residual solution.
To hold or "tack" the PPF in place, a second spray bottle with a "tack" solution of alcohol and water is needed. Lift up the film corner that you want to tack in place and spray the area you want to hold in place with the tack solution. Reapply and squeegee out the liquid towards the OUTTER edge of the film, taking care not to push the solution inwards as it may cause unwanted tacking of the film.
To make tack solution, you'll need an extra and designated spray bottle, 70% to 90% isopropyl alcohol, and water. Mix 900ml of water and 100ml of alcohol in a 9:1 ratio, depending on your bottle size. It's important not to apply alcohol directly to any adhesive as it may cause irreversible hazing to the film.
In summary, slip solution, which is a mixture of soap and water, is crucial when applying PPF as it allows you to place and move the film without it sticking permanently to the surface. Tack solution, made with alcohol and water, is then used to hold the PPF in place. Remember not to apply alcohol directly to any adhesive to prevent hazing. With these solutions, you can achieve a smooth and professional-looking PPF installation.
