Plan your layout

Align window visors and or deflectors with the curvature of the top of the vehicles door frame in order too determine which section is for which door. Generally most sets come with 4 sections two for the drivers and two for the passengers side. Separate the two to save time by using the corners where the front and back doors meet in order to preview fitment.

Use a rag to wipe away any grime or debris that might be on the surfaces where you are applying the vent visors. Included with every purchase is a set of alcohol wipes found with your shipping information and thank you card. The ideal day to install your rain guards is in the dry and warm seasons. Once your surface is cleaned you can begin to install.

Tip! Remove enough of the adhesive backing on each end so that you can pull on it when it is pressed against the vehicle. This technique is shown in the JSP America Rain Guard install instructional video.

This will ensure a much cleaner and tight fit then if you remove all of the backing before pressing the rain guards to the car door. Having a friend help you align them makes this step much easier as some sections are up to 50 inches long. Align the corners of the rain guards with the corners of the vehicle door and try to match the curvature of the top of the door.

Peel away the adhesive backing

At this step, your rain guard should be stuck to the door frame and you shouldn't be adjusting it any more. You should have two strips of adhesive backing hanging out from behind the deflector. While applying pressure peel away the adhesive backing from one end at a time. It helps to only go half way and start from the other end as most front sections have long curves making peeling difficult.

Tip! If the adhesive backing tears off as you peel it away then do not worry, as you still have the other end hanging out in order to finish the job.

Apply heat and pressure

Using your heat gun or hair dryer, apply heat along the entire length of acrylic that is attached to your door frame. After repeating these steps for all of the rain guard sections purchased you can dispose of the alcohol wipes and adhesive backing.

Tip! Keep the heat gun roughly 1-2 inches away from rain guard to avoid any damage or sliding.

Maintenance: Car washes can always cause damage to a rain guard depending on how rough they are to the sides of the vehicle but after two weeks your adhesive should have cured if the weather is fair and the bond will be much stronger.
