Tint your windows by first cleaning them well. Use a spray bottle, sponge, and microfiber cloth to remove dirt. Measure the window carefully and cut the tint film a bit larger than the window size. Spray soapy water on the sticky side of the tint film to help it stick smoothly. Place the film on the window and push out any air bubbles with a squeegee, starting from the center and moving to the edges. Trim the extra film around the edges using a sharp blade to get a neat look. Check local laws about window tinting before starting. Proper tinting can reduce heat by up to 60% and protect against UV rays. Follow these steps for a clean, professional finish.
