How to avoid contamination on the roll-down front passenger windows with a Volvo 850?

Answer 1: Make sure to use the bottom-loading technique if possible.   Answer 2: Be sure to pull the panels before installation to limit contamination.    Answer 3: You should tape the seals if you want to limit contamination.    Answer 4: Cut the sides a bit tighter than normal. This will ensure that you’re not pushing too much into the seals.    Answer: Put the film directly on the glass before sliding it into the seal. This simple trick really reduces contamination.    Answer 5: If you’re using the 2-stage technique, you’ll want to squeegee the bottom half of the window once again before you pull the liner after rolling up the window.    Answer 6: Wipe the side seals if possible.    Answer 7: Spray the film before pulling the liner. This will ensure that there is no static on the doors when you pull the film.    Answer 8: Use hard cards to loosen the seals slightly before installation.    Answer 9: Try misting the air around the window before install, as this can eliminate contamination in a fairly easy way.    Answer 10: Make sure that there are no fans running in your shop during this process, as this can blow dust around and cause contamination.
