Tools & Materials You'll Need
✅ HIC Premium Roof Spoiler
✅ Authentic 3M Automotive-Grade Tape – ensures a secure, long-lasting bond
✅ A Tube of Tape Primer – enhances the adhesive bond for maximum durability
✅ 2 Alcohol Prep Pads – for thoroughly cleaning the installation area
✅ Fitting Kit – includes all necessary hardware for proper installation
✅ Installation Instructions – follow the guide step-by-step for best results
Step 1: Prepare the Surface for Maximum Adhesion
Surface preparation is the foundation of a strong, enduring bond.
✔ Clean Thoroughly:
Use the provided alcohol prep pads to remove all dirt, grease, and wax from the installation area. A spotless surface is essential to ensure that the tape primer and adhesive stick properly.
✔ Dry Completely:
Make sure the area is thoroughly dry - any moisture could compromise the adhesion strength.
✔ Warm Up the Area:
For optimal bonding, install in a warm environment (around 20°C–30°C). If needed, use a heat gun on a low setting to gently warm the mounting area. This helps activate the tape primer and adhesive for a robust bond.
🔹 Common Mistake:
Skipping the cleaning process or working in a cold, damp environment can lead to reduced adhesion and potential peeling over time.
Step 2: Test Fit for Perfect Alignment
Ensure your spoiler fits perfectly before permanent installation.
✔ Dry Run:
Hold the rear window roof spoiler against your vehicle’s rear window to check alignment and overall fit.
✔ Temporarily Secure:
Use the fitting kit’s hardware or masking tape to hold the spoiler in place for a test fit, giving you the freedom to adjust the placement without commitment.
✔ Double-Check Clearances:
Ensure the spoiler doesn’t interfere with other components and that the installation maintains the vehicle’s stylish profile and aerodynamic flow.
🔹 Common Mistake:
Incorrect alignment can lead to increased wind noise and functional issues. Always re-check positioning before final installation.
Step 3: Apply Tape Primer and Secure the Spoiler
This step is critical for a lasting installation.
✔ Apply the Tape Primer:
Cover the cleaned surface with a thin, even layer of the 3M tape primer. Allow it to dry as per product instructions - usually a few minutes - to fully activate the adhesive bond.
✔ Peel Back the Authentic 3M Tape Gradually:
If your spoiler comes with pre-applied adhesive tape, peel back a small section of the liner. Avoid removing the entire backing immediately to maintain control over placement.
✔ Position and Press Firmly:
Begin at one end of the spoiler and slowly peel away the tape liner while pressing the spoiler into position. Apply even pressure along the full length of the spoiler for 30–60 seconds to ensure full contact.
✔ Apply Consistent Pressure:
After positioning, carefully press along all edges to enable complete adhesion with the primed surface.
🔹 Common Mistake:
Removing the tape backing too early can lead to misalignment and weak adhesion.
🔹 Pro Tip:
In cooler conditions, gently warm the adhesive surface with a heat gun to enhance bonding, ensuring longevity and maximum grip.
Optional: Extra Support Parts
Sometimes extra support parts may be included with your installation kit. These components provide additional reinforcement if needed but are completely optional.
✔ No Immediate Installation Required:
You do not need to install these extra support parts during the initial setup. They can be stored safely for future use if additional reinforcement becomes necessary.
✔ Use as Needed:
Keep these parts on hand for flexibility and peace of mind. They’re available if extra stability is required later on.
Step 4: Allow the Adhesive to Cure for Maximum Durability
Patience is key for a secure, long-lasting installation.
✔ Curing Time:
Allow at least 24 hours for the adhesive to cure completely. Avoid driving, washing, or exposing the spoiler to heavy moisture during this curing period.
✔ Final Inspection:
Once cured, gently tug at the spoiler’s edges to ensure there are no gaps or loose spots. A well-cured bond should feel solid and continuous.
✔ Operational Check:
If the spoiler interacts with any moveable parts or negatively affects other components, check and adjust accordingly.
🔹 Common Mistake:
Washing or exposing the vehicle to rain too soon can compromise the adhesive bond and lead to premature lifting.
Troubleshooting Common Issues
If you encounter issues during or after installation, consider these solutions:
🛠 Issue: Spoiler Peeling Off
✔ Solution: Reassess your cleaning and surface preparation. Ensure the area was thoroughly cleaned, dried, and primed. Apply extra heat if necessary and firmly press down the spoiler again.
🛠 Issue: Misalignment Causing Increased Wind Noise
✔ Solution: Use the fitting kit or masking tape during the test fit to adjust the positioning. Even slight misalignment can create turbulence; recheck and reposition if needed.
🛠 Issue: Poor Adhesive Bonding
✔ Solution: Verify that the installation area was 100% clean and dry before primer and adhesive application. If the bond is weak, rewarm the area gently with a heat gun and press down the spoiler once more.
