Thoroughly clean the windscreen to remove all dirt, grit and grease. Be careful which product you use to clean the glass, as some will leave a residue behind that will prevent the sticker from adhering well. Most alcohol-based glass cleaners evaporate so will be best for this.

Measure down from each side of the top of the windscreen and apply a little masking tape, to mark the same length at each side of the windscreen. This will help ensure the strip is applied as straight as possible.

Remove the backing paper from the sunstrip and apply a thin spray of soapy water to it as well as the top of the windscreen (don't use too much soap in your water. Less is more here).

Apply the sunstrip to glass leaving the excess at the sides and top. The soapy water will allow movement of the strip to ensure it's placed correctly.

Squeeze out excess water and air bubbles from under the strip. The side of a credit card wrapped in a microfibre cloth is a handy tool for this. You can pin prick any bubbles that won't go away and press flat if they’re a real pain (We do sell squeegees which are perfect for this task, find them in the sunstrip section)

Trim off excess vinyl around the glass carefully with a new sharp blade. When it is fitted and you are happy, leave it to totally dry before driving off (you don’t want it flying off halfway down the road!)

After fitting the sunstrip, use a heat gun or hairdryer on a low–medium setting to gently warm the vinyl. Keep the heat source moving to avoid damage. The heat helps the adhesive bond to the glass more effectively — press down with a squeegee or cloth as you go to ensure a firm, bubble-free finish. You can now slowly remove the masking tape from the sunstrip to reveal the stencil cut text.
