Windshield Decal Installation Instructions


The following are the application instructions recommended by Auto Trim DESIGN. These procedures must be followed prior to any consideration by Auto Trim DESIGN and/or its graphic manufacturers in regard to replacement or credit. Failure to follow instructions listed below in bold red letters may result in product failure and be considered non-warrantable.

Graphic Materials Information
Storage and Rotation:
Stock rotation and climate-controlled storage are important. Age and temperature extremes degrade the adhesive and can dramatically reduce its effectiveness. Product should be used within the recommended storage life of two years. In addition, product should be stored in an environment between 60 and 90 degrees Fahrenheit.
Temperature Recommendations:
Surface temperature should be between 50 and 90 degrees Fahrenheit before attempting the installation. As a general rule, if the surface is hot to the touch it's over 90 degrees Fahrenheit. Adhesive becomes brittle when it gets too cold and gummy when it gets too hot. Applications outside the recommended range of 50 to 90 degrees Fahrenheit reduce the adhesives' ability to perform. 
Preparation & Cleaning Procedures
Cleaning Procedures:
All surfaces are contaminated to some degree. To ensure good adhesion to any vehicle surface, it is critical that you follow these recommended procedures in decontaminating and preparing the surface prior to any vinyl product installation. A clean, lint free towel or cloth must be used between each of the cleaning steps to prevent cross-contamination.
  • Remove heavy road grime or tar using our Rapid Prep cleaning solution.
  • When a silicone substance or residue is suspected, wash and rinse the contaminated area with liquid dish detergent and warm water. Dry the surface with a clean, lint free towel or cloth.
  • After the detergent wash simply finish the process by wiping down the entire area with our Rapid Tac or Rapid Tac II application fluid. Again use a clean, lint-free towel or cloth.

A note about Windshield Cleanliness

The prior use of synthetic protectants and silicones (i.e. Armorall, Son of a Gun, Rainex, etc.) on the substrate can result in adhesive difficulties. Therefore, special substrate cleaning with a silicone removal agent (i.e. 3M #08984 General Purpose Adhesive Cleaner, Denatured Alcohol, etc.) may be required, perhaps repeatedly. A final cleaning with DENATURED ALCOHOL is recommended with thorough drying of surface. Clean surface until all slick feel on the substrate is gone. Always test any cleaner on an inconspicuous area first for any reactions to surface finishes.

Installation Guidelines
Application Procedures:
  • The base material is vinyl. Because vinyl is a pressure-sensitive product, direct pressure to the product is very important. Please use your thumb or a soft, non-marring tool to apply pressure.

Illustrated Installation Procedures


Step 1

After thoroughly cleaning the windshield surface, find and mark it's center with a small piece of tape or white grease pencil. Take care not to use the Rear View Mirror mount for reference as not all mirrors are placed at exact windshield center.

Step 2

Locate and mark center of the Windshield Decal. Center can easily be found by folding the decal lengthwise in two . The resulting crease is center.

Step 3

Once centers are found, place decal onto windshield so as to become familiar with desired placement.

Step 4

Recommended method of installation is the Center Hinge. This is achieved by carefully removing a 2-3" portion of the backing paper from the center as shown.

Step 5

Once a portion of the center is removed, simply fold back each side of the backing paper approximately 1" (25.4mm) onto itself.

Step 6

Then, turn the decal over and carefully set it in the desired location, making sure it's centered. When placed correctly, stick the center exposed area down with your thumb.

Step 7

Once "hinged", apply each side of the decal from the center with an application squeegee or soft non-marring tool.

Step 8

To remove the application tape, peel SLOWLY at a sharp (180) angle. If the vinyl appears to be lifting, gently push the application tape in the opposite direction from which you were pulling and re-squeegee that area. If after removing the application tape, air bubbles are apparent, puncture the vinyl with a pin or needle (DO NOT USE a knife or razor blade) and squeegee out the air towards the puncture.

Step 9

Step back and ADMIRE!


Exterior Graphic Care

Today's finest pressure-sensitive vinyl materials have been used to create your new graphics. These graphics require little maintenance and should be treated similarly to a painted surface.

Do wash your graphics with plain soap and water or any commercially made car wash soap. Rinse thoroughly.

Do keep high pressure nozzles at least 18 inches from the edge of the graphics. High pressure spray may cause the edge of the graphic to peel.

Do test any cleaning solution on a small section of the decal before using. Be sure to read the solution's directions and warning notices that may apply to Vinyl Graphics.

Don't use any aromatic solvents such as acetone, M.E.K., toluene, paint thinner, or lacquer thinner on your graphics. Any solvent may soften the vinyl material or smear colors.

Don't overcoat the graphics with clear paint (voids manufacturer's warranty).

Don't let gasoline or other fuels drip or stay on graphics for any length of time. If a spill occurs, wipe off and rinse with water immediately.

Don't paint over the graphics.

Don't apply wax over graphics. Wax products generally contain petroleum distillates, which can damage vinyl graphics. The only product we suggest for use on vinyl graphics is Rod & Custom Show Gloss Creme.

Care and caution should be taken when storing your vehicle. Vinyl graphics and other items such as dashboards, tires and flexible rubber products will have a shorter life expectancy when exposed to severe heat and sunlight. Protection of graphics from prolonged direct sunlight will insure an extended life.

Note about Windshield Lettering Products: There is no warranty on windshield lettering products against peeling, wiper blade damage, ice scraper damage, or any other type of damage that may occur. While these occurrences all prove to be out of our control, rest assured that the vinyl materials used are Premium grade with a life expectancy in regard to colorfastness of 5-7 years.
