Before you Start

Please take your time to check if the sun strip has any defects such as rips or cuts. If there is any damage we will offer you a free replacement! We cannot guarantee this service once the backing fo transfer tape were removed off the product.

Clean your Windshield

Cleaning car windshield

Remove any loose dirt, bugs and other possible contamination from the windshield. Next, degrease the windshield with some cleaner. Rubbing alcohol or Windex will work great.

Align the Sun Strip

Position sun strip (banner) on the windshield

Unpack the sun strip and set it over the windshield. Use ruler or other measuring tool to ensure the sun strip is centered on top of windshield. Sun strip should cover all the rubber weather strips of the top part of the windshield. Use masking tape to mark desired position of the sun strip on your vehicle.

Expose the Adhesive Side

Remove the backing of the Sun Strip to expose the adhesive side

Separate the backing of the sun strip to expose the adhesive vinyl side. Mix 1 drop of dish soap per 32 oz of water in a spray bottle. Spray over the adhesive side of the sun strip, roof and windshield. Additionally wet the opposite (outside) surface of the sun strip with transfer paper overlay. This will help work out the creases.

Set Flat over the Wet Windshield

Set sun strip over the wet windshield

Position the sun strip on the windshield and align with respect to the tape marks made earlier. It is much easier to have two people here. One on each side of the vehicle. While the sun strip adhesive side is wet, you can re-position it multiple times on the windshield. Ensure the sun strip sits flat with no folds. With a spreader or credit card, squeeze water and air bubbles from in between of the windshield and the sun strip. Go from the center of the sun strip towards its sides.

Dry with Paper Towels and Remove Transfer

Removing the transfer tape

Use a paper towel roll to absorb all the moisture on top and around the sun strip. Give it about 10 minutes to dry. Next, remove the transfer paper from the face of the sun strip. Peel back against the glass, avoid pulling the transfer tape up (see picture above).

Cut Sun Strip along the Windshield Seal

Cutting sun strip edges

Use the spreader and knife to work on the edges of the sun strip. squeeze any leftover moisture from under the edges and use knife to trim the sun strip along the windshield edge (or rubber weather seal). Please allow 24 hours for the banner to dry. Otherwise it can get torn at higher speeds on a highway.
