Polarized adhesives offer many benefits, including UV protection and privacy. You will want to access your skills before trying this project for yourself.

You will need to:
  • Marker penknife.
  • Dish soap
  • Bottle with spray.
  • Hair dryer
  • Small sponges
  • X-Act blades
  • Razor blades for men
  • Polarized film
  • Hot air guns

Gather the following tools and materials: polarized stickers, X-acto blades, knives, a hair dryer or heat gun, 4-inch brushes, small sponges, a 4-inch hard card, and a spray bottle filled with a mixture of detergent and water.


Cut the sticker with the shape of the windows, leave the excess part to the side. Some brands or companies offer pre-cut adhesives that you can buy for specific vehicle models.


Spray the side window with the soap and water mixture.


Use a razor and pass it through the sides of the window to remove any residue.


Use a 4-inch squeegee to get rid of any residue from top to bottom.


Apply the polarized adhesive to the window . Leave 1/4 cm to 1/16 cm from the top edge of the window without ink. This will be covered when the window and the door are closed.


Use the tool to push the polarized adhesive into the interior rubber edges of the window .


Use the card to make sure the sticker goes into all corners.


Take a heat gun or blow dryer in one hand and a squeegee in the other, heat the top part on one side and pass the squeegee over the ink on the other side with a horizontal movement, this ensures that removes all remaining moisture between the adhesive and the glass.


Use the same procedure to apply the polarized adhesive on the front windshield. Note: In some communities it is illegal to apply a polarized adhesive to the front windshield.


Follow steps 3 and 5 to apply the adhesive on the back window . Do not use the knife to prepare the rear window because the blade may damage the rear defroster.

Place the first panel on the bottom, the second panel on top of the first, the third panel on top of the second, and so on. Identify defroster lines where two panels overlap.


Cut the adhesive over the defroster lines.
