Make sure you use shampoo and water or a specified glass cleaner.
Before you cut use your measuring tape to measure the surfaces that you will be tinting.
You can cut the tinting into the size that you measured for each individual window.
Next you will want to spray the application solution onto the glass and remove the adhesive backing of the film. Make sure the sticky part is facing the window.
Take your hand squeegee and smooth out any bubbles and creases. Use your spray bottle full of hot water to spray on the glass to make it easier for your squeegee to smooth it out.
