💡 Pro Tip: Gather all tools before starting. Having everything ready makes the installation process smoother and reduces the risk of rushing.

1. Wash the Installation Area
   • Use car soap and water to wash the entire trunk/roof area
   • Remove all dirt, dust, road grime, and debris
   • Pay special attention to the edges where the spoiler will mount
   • Rinse thoroughly with clean water
2. Dry Completely
   • Use clean microfiber towels to dry the area
   • Ensure no water droplets remain
   • Let air dry for 2-3 minutes
   • Check for any remaining moisture

3. Apply Isopropyl Alcohol
   • Use included alcohol wipes or spray isopropyl alcohol on microfiber towel
   • Wipe the entire installation area thoroughly
   • This removes wax, oils, and any remaining residue
   • Use a clean section of towel for final wipe
4. Let Dry
   • Allow alcohol to evaporate completely (2-3 minutes)
   • Surface should be completely dry before next step
   • Do not touch the cleaned area with bare hands

⚠️ Critical Step: The adhesion promoter significantly improves bond strength. Don't skip this step!

5. Use Adhesion Promoter Wipe
   • Open the included adhesion promoter wipe packet
   • Wipe evenly across the entire installation area
   • Apply in one direction for even coverage
   • Ensure complete coverage of mounting surface
6. Drying Time
   • Let adhesion promoter dry for 1-2 minutes
   • Surface will appear slightly tacky when ready
   • Do not touch the treated area

✅ Preparation Complete! Your surface is now ready for spoiler installation. The next 30 minutes are critical for proper bonding.

🎯 Goal: Determine exact spoiler position before removing adhesive backing.

1. Position the Spoiler
   • Carefully place spoiler on trunk/roof WITHOUT removing adhesive backing
   • Align with trunk edge or roof line
   • Ensure equal spacing on both sides
   • Check alignment with taillights (for rear spoilers)
2. Check from Multiple Angles
   • Step back and view from rear of vehicle
   • Check from both sides for symmetry
   • View from above to ensure centering
   • Ask helper to confirm alignment if available
3. Mark Position with Tape
   • Once satisfied with position, mark edges with small pieces of painters tape
   • Place tape markers at front, rear, and sides of spoiler
   • These markers will guide final installation
   • Take a photo for reference

💡 Pro Tip: Take your time with test fitting. Spending an extra 5 minutes here can save you from a crooked installation that's difficult to fix later.

1. Heat the Adhesive Tape
   • Use hair dryer on LOW-MEDIUM setting
   • Heat the 3M VHB tape on the spoiler for 20-30 seconds
   • Move dryer in circular motion for even heating
   • Tape should feel warm to touch (NOT hot - max 40°C/104°F)
2. Why Heat?
   • Activates adhesive for stronger initial bond
   • Makes tape more pliable for better surface contact
   • Especially helpful in cooler temperatures
   • Improves overall bond strength

⚠️ Warning: Do NOT overheat! Excessive heat can damage the adhesive. Warm to touch is perfect.

3. Peel Off Red Backing
   • Carefully peel off the red protective film from 3M tape
   • Start from one corner and peel slowly
   • Avoid touching the exposed adhesive surface
   • If tape accidentally touches itself, do NOT try to separate - use new tape
4. Work Quickly
   • Once backing is removed, install within 2-3 minutes
   • Adhesive begins to cure upon air exposure
   • Have helper ready if using one

5. Align with Tape Markers
   • Carefully position spoiler using your tape markers as guides
   • Start from one end and work across
   • Ensure perfect alignment before making contact
   • Once adhesive touches, repositioning is very difficult
6. Make Initial Contact
   • Gently lower spoiler onto surface
   • Start from center and work outward
   • Ensure no air bubbles trapped underneath
   • Check alignment one final time before pressing
7. Apply Firm Pressure
   • Press firmly along entire length of spoiler
   • Apply even pressure for 30-60 seconds
   • Use palm of hand, not fingers
   • Work from center outward to eliminate air bubbles
8. Press All Contact Points
   • Ensure every part of adhesive tape makes contact
   • Pay special attention to edges and corners
   • Apply extra pressure to high-stress areas
   • Total pressing time: 60-90 seconds

9. Apply Support Tape
   • Use painters tape to hold spoiler in place during curing
   • Apply tape every 6-8 inches along the spoiler
   • Tape from spoiler to trunk/roof surface
   • Don't apply too much tension - just support
10. Check Final Alignment
    • Step back and verify alignment one last time
    • Make minor adjustments if needed (within first 30 seconds only)
    • After 1 minute, adhesive begins to set

🎉 Installation Complete! Your spoiler is now installed. The adhesive will continue to cure over the next 48-72 hours.

⚠️ Most Important 24 Hours:

• Keep Painters Tape: Leave support tape in place for full 24 hours minimum
• Avoid Water: No washing, no rain exposure if possible
• Gentle Driving: Keep speeds under 40 mph for first 6 hours
• No Touching: Resist urge to test bond strength
• Garage Parking: Park indoors if available

1. Wait Full 24 Hours Minimum
   • Preferably wait 48 hours for maximum safety
   • In cold weather (below 15°C), wait 72 hours
2. Remove Tape Carefully
   • Peel tape slowly at 45-degree angle
   • Pull away from spoiler, not upward
   • If tape is stuck, use hair dryer to warm slightly
3. Inspect Installation
   • Check all edges for proper adhesion
   • Look for any gaps or lifting
   • Verify alignment is still perfect

Cold Weather Installation (Below 15°C/59°F):

• Extend curing time to 96 hours (4 days)
• Use heat gun/hair dryer more liberally during installation
• Park in heated garage if possible
• Consider waiting for warmer weather if below 10°C/50°F

Hot Weather Installation (Above 30°C/86°F):

• Work in shade or garage to avoid overheating adhesive
• Adhesive may cure faster (good!)
• Be extra careful with alignment - less working time
• Keep vehicle out of direct sun for first 24 hours

Symptoms: Edges lifting, poor adhesion, spoiler feels loose

Causes:

• Surface not cleaned properly
• Adhesion promoter not used or not dried
• Installation in cold weather
• Insufficient pressure applied
• Touched adhesive surface before installation

Solutions:

1. If within first hour: Carefully remove, clean surface again, apply new tape
2. If after curing: Apply additional 3M VHB tape to problem areas
3. Use heat gun to warm adhesive and apply firm pressure
4. Secure with painters tape for additional 48 hours

Symptoms: Spoiler crooked, uneven spacing, not centered

Prevention:

• Always do thorough test fitting
• Use tape markers
• Have helper verify alignment
• Take your time - don't rush

Solutions:

1. Within 30 seconds: Carefully lift and reposition (one chance only)
2. Within 5 minutes: Very difficult - may damage adhesive
3. After curing: Must remove completely, clean, and reinstall with new tape

Symptoms: Visible gaps, hollow sound when tapped

Causes:

• Insufficient pressure during installation
• Uneven surface
• Debris trapped under spoiler

Solutions:

1. Apply firm pressure to affected area
2. Use heat gun to warm area, then press firmly
3. If large bubble: May need to remove and reinstall
4. Small bubbles (under 1cm) usually not a problem

When: After removing spoiler or cleaning up mistakes

🏆 Expert Installation Checklist

Follow this checklist for guaranteed success:

• ☐ Weather checked - dry, 15-30°C
• ☐ All tools gathered and ready
• ☐ Vehicle washed and dried
• ☐ Surface cleaned with alcohol
• ☐ Adhesion promoter applied and dried
• ☐ Test fit completed and marked
• ☐ Helper available (if needed)
• ☐ Adhesive tape heated (optional)
• ☐ Alignment verified before pressing
• ☐ Firm pressure applied for 60+ seconds
• ☐ Painters tape applied for support
• ☐ 24-48 hour cure time planned

Q1: Can I install a spoiler in cold weather?

A: Yes, but with precautions. Minimum temperature is 10°C (50°F). Below 15°C (59°F), extend curing time to 96 hours and use heat gun liberally. Ideal temperature is 20-25°C (68-77°F). If possible, warm your garage or wait for warmer weather.

Q2: What if it rains during the curing period?

A: Light rain after 24 hours is usually OK. Heavy rain or car washing should be avoided for 48-72 hours. If rain is forecasted, either delay installation or park in covered area. Water exposure during first 24 hours can significantly weaken bond.

Q3: How strong is the 3M VHB tape bond?

A: When properly installed, 3M VHB tape can hold 10+ kg (22+ lbs) and withstand speeds over 150 mph. The bond is permanent and often stronger than the materials being bonded. Many automotive manufacturers use VHB tape for exterior trim and badges.

Q4: Can I remove and reinstall if I make a mistake?

A: Within the first 30 seconds, you have ONE chance to carefully lift and reposition. After that, the adhesive begins to cure and repositioning will damage the bond. If seriously misaligned, it's better to remove completely, clean surface, and install with new adhesive tape. Contact Tesery for replacement tape.

Q5: Do I need a helper for installation?

A: Not required but highly recommended for:

• Roof spoilers - Helper makes alignment much easier
• Side skirts - Extra hands helpful for long pieces
• First-time installers - Helper can verify alignment
• Rear trunk spoilers - Can be done solo but easier with help

Q6: Will this void my Tesla warranty?

A: No. Installing exterior accessories with adhesive tape does not void your Tesla warranty. The Magnuson-Moss Warranty Act protects your right to modify your vehicle. However, if a spoiler installation causes damage (extremely rare with proper installation), that specific damage may not be covered.

Q7: How do I remove a spoiler later?

A: Use a heat gun to warm the adhesive (medium heat, keep moving). Slowly work a plastic pry tool under the edge. Pull spoiler away slowly while continuing to heat. Clean residual adhesive with 3M Adhesive Remover or Goo Gone. Never use metal tools or excessive force.

Q8: Can I go through a car wash after installation?

A: Wait minimum 72 hours (3 days) before hand washing. Wait 7 days before automatic car wash. After full cure, all car washes are safe. Avoid high-pressure washers directly on spoiler edges for first month.

Q9: What if I don't have isopropyl alcohol?

A: Isopropyl alcohol (70%+ concentration) is critical for proper surface preparation. It's available at any pharmacy or grocery store for $2-5. Do NOT substitute with other cleaners - they may leave residue that prevents proper bonding. The included alcohol wipes are usually sufficient, but having extra is recommended.

Q10: How long will the spoiler last?

A: With proper installation and care:

• 3M VHB adhesive: 10+ years bond strength
• Carbon fiber spoilers: Lifetime durability with proper care
• ABS spoilers: 10+ years with UV protection
• Finish/coating: 3-5 years before potential fading (with UV protection)

Regular maintenance (washing, waxing) extends lifespan significantly.
