This limited product warranty covers STEK paint protection films.

Warranty Coverage

Valid from date of purchase. Covers defects in materials and manufacturing against yellowing, bubbling or cracking.

This warranty does not cover damage caused by misuse, accidents, misapplication, normal wear and tear, dents from road debris impact, collisions, and/or intentional damage of any kind.

To file a claim, contact the original installer/dealer first.  If unable to do so, contact STEK using the website www.stekautomotive.com, or www.stek-usa.com if in the United States.

You must retain a copy of this warranty and proof of purchase identifying the name of the original installer/dealer, purchase price, product (e.g., DYNOshield), and coverage areas. These documents are needed to process your claim.

Some installers may choose to offer, on their own behalf, different or additional warranties or remedies, beyond the limited warranty and limited remedy offered by STEK. Check your state and local laws before installing film on headlamps, as each state has different policies for aftermarket accessories.  STEK does not cover paint protection film installed on headlamps and is not responsible for any resulting damages or fines. 

For valid claims, an authorized STEK installer shall remove the defective film and reapply new product(s) to areas determined by STEK to be covered by the warranty.


Note that some state laws do not permit limitations on the length of an implied warranty. In this case, the limitation above may not apply.

Except where prohibited by law, STEK and the installer/dealer of the product(s) shall not be liable for any loss or damage arising from the use of the product(s) whether direct, indirect, special, incidental, or consequential, regardless of the legal theory asserted, including warranty, contract, negligence, or strict liability. Note that some states/regions/countries do not allow the exclusion or limitation of incidental or consequential damages, so the aforementioned limitation or exclusion may not apply.

The warranty and remedies above are available exclusively for the described product(s). STEK installers/dealers cannot modify or extend this limited warranty. STEK shall be solely responsible for determining the validity of all claims and reserves the right to deny claims that do not meet the above criteria. Replacement of the defective film, including labor, is the exclusive remedy. Liability does not extend to any other damages: incidental, consequential, or otherwise. 

The following list is a summary of best practices for working with any top-coated thermal polyurethane (TPU) paint protection film. These are included for your review. STEK strongly recommends that you follow these guidelines to ensure product quality upon delivery and handling, and to reduce wasted time and material.

1. Do not put undue pressure on the surface of the film while it is still on the roll, as pressure marks may form.

2. Handle the carton with care to avoid pressure marks from careless handling.

3. Gloss may fade due to pressure, long-term storage, and high temperatures, which is typical of TPU film. The gloss may be recovered by using a heat gun on the affected area. To protect gloss prior to installation, STEK uses a protective GLOSS-ENHANCING sheet on the surface of the top coat.

4. The product should be stored in an environment with temperatures below 90°F and a relative humidity between 40% and 60%.

5. STEK paint protection film should be used within one year from the date of purchase.

6. Repackaging a roll of film into a box bigger or smaller than the size of the roll can damage the film. Doing so may result in pressure marks, faded gloss, embossing marks, etc. STEK therefore recommends using the original box and packaging for storage.

7. When rewinding or cutting in order to repackage the film, note that surface marks (e.g., small dots, twists, etc.) may appear on the surface due to dirt or dust contamination. If repackaging, ensure that your workspace is clean.

8. After using part of a roll of film, do not repack it loosely. Keep the film as it was originally packaged—rolled tight and held in place by taping. As STEK films have surface protection sheets, note that tunneling may occur if the roll is not rewound tightly or rewound in the reverse direction.

9. Adhesive characteristics may change between seasons if the application environment is not climate-controlled. This is typical of the material. Particularly in cold weather, apply the film only in environments with temperatures higher than 50° F.

10. Generally, water mixed with a neutral detergent or IPA (isopropyl alcohol) may be used as a pre-handling liquid before applying the film. Initial adhesive tack may vary depending on the ratio of IPA to water.

11. Contact the manufacturer if using PPF for non-automotive purposes. Material size, packaging, and adhesive specifications may need to be changed.

12. Note: STEK is not responsible for damage caused by mishandling, improper storage, recutting, repacking, not using a sponge core, or storage for more than one year.

The following list is a summary of best practices for installing and caring for STEK top-coated thermal polyurethane (TPU) paint protection films. They are included for your own review and for review with your customers. STEK strongly recommends that you follow these guidelines to ensure quality installation.

1. Due to its self-healing abilities, light scratches on STEK top-coated paint protection films (PPFs) may be removed by applying hot water or a heat gun over the affected area(s). Note that if a scratch has penetrated the top coat, it will not self-heal. This is typical of any top-coated PPF.

2. During installation, take care to avoid scratching from installation tools. We recommend using a rubber squeegee for installation (e.g., a yellow or green Turbo squeegee). Even with the use of a rubber squeegee, scratches may occur. Test your tools before installation to determine whether they are safe for use.

3. Installation should take place in a clean area free of airborne dust and other particulates, which could result in surface scratches.

4. Test all waxes or after-market sealants before application to PPFs. Not all products are compatible with PPF top coats. Extremely hydrophobic PPF top coats may interfere with the application of waxes or other coatings.

5. STEK recommends hand-washing cars protected with PPF. While the top coat may have self-healing abilities, using automatic car washes increases the likelihood of surface scratching. Though minor scratches may self-heal, deeper scratches may remain if they have penetrated the top coat.

6. Although STEK PPF is highly resistant to cracking, lift lines, and “chicken-skinning,” applying too much force/stretching may damage the film. While STEK PPF offers sufficient flexibility for installation in tight corners, depressions, and other complex areas, the material does have its limits. In order to determine such limits, which may vary based on individual application methods, we recommend testing the stretchability of the PPF prior to your first installation. Note that a heat gun may be used during stretching to increase flexibility.

7. Maintenance & Care Instructions (PPF & top-coated PPF)

a. Do not wash the vehicle for 48 hours following installation.

b. Avoid directly spraying the edges of the PPF with a pressure washer or nozzle. Doing so may lift the edge of the film. If using a high-pressure washer, keep the nozzle at least 36 inches above the film’s surface.

c. Do not use pigmented waxes, abrasive waxes, or waxes containing naphtha or kerosene.

d. Do not use abrasive pads or harsh chemicals on the film.

e. If desired, wax the car and film at least once every 6 months after testing for compatibility.

f. Remove stains as soon as possible. Use isopropyl alcohol to remove stubborn stains. Avoid cleaning the film in direct sunlight or in high temperatures.

Caution: Dirt, debris, and stains left on the film may discolor the film if not removed immediately. Take care to prevent discoloration, which may be more noticeable on lighter-colored cars. Advise vehicle owners of proper maintenance procedures.

8. To remove the film, pull the film from a corner at an angle less than 90° from the surface of the car. If the film has been installed for a number of years, it may be more difficult to remove. In that case, a steamer, heat gun, or hair dryer may be used to soften the adhesive. After removing the film, adhesive residue may remain on the vehicle body. This residue may be easily removed using the STEK adhesive remover.

Caution: When removing DYNOblack, DYNOblack-matt, DYNOblack-carbon, DYNOsmoke, DYNOshade, or DYNOfancy, colored adhesive residue may remain on the vehicle body. This is caused by the structure of the product. In that case, simply use the STEK adhesive remover to remove such residue and any remaining color.
