⚠️ IMPORTANT FITMENT NOTICE

While this 17cm x 7.5cm (Approx. 6.7" x 3") customized size fits many standard shark fin antennas, it does NOT fit all vehicle models.

🔬 ADHESIVE SCIENCE: The 4229P Standard

3M™ 4229P is engineered with a unique Viscoelastic acrylic foam core.

• Gap Filling: Unlike thin office tapes, the 4229P's 0.76mm core allows it to "fill" minor gaps on curved automotive surfaces.
• Thermal Expansion: Compensates for different expansion rates of paint and plastic in extreme sun.
• Vibration Damping: Absorbs mechanical energy, preventing trims from loosening.

Best Applications

Shark Tail Antennas: Customized 17x7.5cm size fits many automobile roof shark fin antennas (Measure First).
Exterior Trims: Door moldings, badges, and spoilers.
Weatherproof Seal: Permanent protection against water and salt.

⚠️ MUST READ: Pressure Sensitive Adhesive (PSA)

IMPORTANT FOR SUCCESSFUL BONDING:

Not a Tacky Glue: This tape is NOT traditionally "sticky" to fingers. It requires FIRM PRESSURE to activate the bond.
Prep (IPA): Clean surface with 50% Isopropyl Alcohol before application. Must be wax-free and bone dry.
Adhesion Promoter: For plastics like PP or EPDM, you MUST use a 3M Promoter for a permanent bond.
Wait 72 Hours: Final strength is achieved after 72h. Avoid car washes during this period.

Application Steps

1. CLEAN: Decontaminate the car roof surface and the antenna base with IPA. Dry thoroughly.

2. APPLY: Position tape carefully. Do not touch the adhesive.

3. PRESSURE: Use firm hand pressure (15 PSI) to activate chemical bond.

4. DWELL: Allow 72 hours for the adhesive to fully "wet-out".
