I installed the Tesla PPF for the rear doors today. This was my first time installing PPF.
Steps:
1) Read the Tesla PPF kit installation pamphlet.
2) Review items in kit, locate additional items needed to install the PPF (spray bottle, baby shampoo, microfiber cloths, work light, flash light, something low to sit on.)
3) Wash vehicle (my Model Y was only slightly dirty from some rain last Thursday, I decided to use Optimum No Rinse (ONR.)
4) After washing my Model Y with ONR I used Windex and a micro fiber cloth on the area of rear doors where the PPF is installed (Windex contains ammonia, dissolves wax. I wanted to remove any remaining car wax from the door panels.)
5) After washing door panels with Windex I went over the panels a second time with some Invisible Glass (contains alcohol.) I probably did not need to do this last cleaning in preparation for the PPF.
6) Cut the 3M paper sheet backing with the PPF down the middle of the paper so the two halves of the PPF are now separated. Place each piece of PPF film with the backing paper against the door panel to get an idea of how it is supposed to be oriented on the panel. (Left can appear right, up can appear to be down; repeat as many times as necessary until you are 100% certain that you know which sheet of PPF goes on the driver's side (left side) and the passenger side (right side.)
7) Prepare the slip solution of 85% water (I used tap water) and 15% baby shampoo; pour the mixture into a clean spray bottle (prepare 8 to 10 ounces of the slip solution.)
8) Wet the part of the door panel where the PPF will be installed thoroughly with the slip solution; wet the exposed side of the PPF with the slip solution; carefully start peeling the PPF away from the paper backing applying more of the slip solution to the tacky side of the PPF as you go.
9) Carefully place the PPF against the door panel. While the PPF is wet you can easily move the PPF around for final placement. Be sure that the edges of the PPF do not overhang the bottom edge or rear edge of the door. (I estimate I left 1/16" of door panel exposed at the bottom edge and rear edge of the PPF.)
10) Apply more of the slip solution to the front surface of the PPF; use the provided squeegee tool to press out any bubbles. (This is the most time consuming step.) The large air bubbles are easy to see, remove. There may be multiple small air bubbles underneath the PPF. This is where a flashlight helps highlight the remaining small bubbles.
11) If the exposed surface of the PPF starts to dry apply more slip solution before using the squeegee to remove any remaining bubbles.
12) Check the fit of the PPF along the bottom edge and the rear edge of the door for any final adjustment. After a few minutes it will become harder to slide the PPF around as the adhesive begins to set.
13) Dry off the PPF and use the flashlight to look for any remaining small air bubbles. Always apply slip solution to the PPF if you have to use the squeegee to remove any remaining air bubbles. Make sure all of the air bubbles, large and small, have now been removed from beneath the PPF.
14) Wipe off the PPF and the surrounding door with a damp microfiber cloth. Dry the door panel being careful to avoid contacting the newly installed PPF.
15) Wait 24 hours before exposing the newly installed PPF to any rain, water etc.
