1. 3M VHB Tape 5952: Top Pick
3M VHB 5952 is the industry standard for bonding spoilers without mechanical fasteners. In our research, it consistently outperforms other tapes in shear strength and temperature range. Owner feedback confirms it holds spoilers securely at highway speeds and through weather extremes. However, it demands meticulous surface preparation: any dirt or wax residue will compromise the bond.
This tape is best for permanent installations where you can prepare the surface properly. Skip it if you need a temporary hold or plan to remove the spoiler frequently, as removal can damage paint.
- Pressure sensitive acrylic foam provides immediate holding power
- Withstands temperatures from -40F to 300F
- Excellent UV and moisture resistance for outdoor use
Pros: Strongest adhesion among foam tapes; Long lasting outdoor durability
Cons: Requires clean, smooth surface for best bond
2. Gorilla Heavy Duty Double Sided Mounting Tape: Best Value
Gorilla Heavy Duty tape offers a strong bond at a lower cost per foot compared to premium tapes. In our evaluation, it performed well on moderately curved spoilers and held up to rain and sun. Owner reviews note it works fine for lightweight spoilers but may struggle with heavy or large ones.
This tape is a good choice for budget conscious buyers or temporary spoiler mounting. However, if you have a heavy spoiler or live in a very hot climate, consider a higher temperature rated tape.
- Thick foam conforms to irregular surfaces
- UV resistant and waterproof
- Can hold up to 30 pounds per square inch
Pros: Great value for length; Good adhesion on curved spoilers
Cons: Not as strong as 3M VHB under extreme heat
3. Tesa 4965 Extra Strength Double Sided Tape: Premium
Tesa 4965 is a professional grade tape often used in automotive assembly. We found its initial tack superior to many competitors, making installation easier. It bonds well to clear coat and holds spoilers securely. However, its thinness means it doesn’t fill gaps well if the spoiler doesn’t sit flush.
This tape is ideal for spoilers that have a perfect fit against the trunk. Skip it if your spoiler has uneven contact or if you need a thicker tape to bridge imperfections.
- High initial tack for instant grip
- Excellent adhesion to painted surfaces
- Thin profile for tight gaps
Pros: Very strong initial grab; Thin and nearly invisible
Cons: Expensive per foot; Less gap filling ability
4. 3M Exterior Attachment Tape 03614: Versatile
3M 03614 is a solid choice for smaller spoilers or as a supplementary tape. In our research, it provides reliable outdoor durability and is easier to find on Amazon. However, its narrow width means you need to apply multiple strips for a large spoiler, which can be tedious.
This tape works well for lightweight spoilers or for securing edges. It is not recommended for heavy carbon fiber spoilers or applications where maximum strength is needed.
- Designed for exterior trim and emblems
- Holds up to 5 pounds per linear inch
- Works on metal, plastic, and painted surfaces
Pros: Good all around performance; Easy to cut and apply
Cons: Narrow width may require multiple strips; Not as strong as VHB
5. XFasten Professional Double Sided Tape: Budget Friendly
XFasten Professional tape is a budget option that works for light duty spoiler mounting. In owner feedback, some users report it holds well initially but may fail after a hot summer. We found it acceptable for small, lightweight spoilers but not for permanent installations.
If you need a temporary solution or have a very small spoiler, this tape might suffice. Skip it for any spoiler that will be exposed to direct sunlight or high speeds.
- Long length for multiple projects
- Transparent design
- Water resistant
Pros: Very low cost per foot; Long roll
Cons: Adhesion weakens in heat; Not recommended for heavy spoilers
6. Nexcare Extreme Double Sided Tape: Medical Grade
Nexcare Extreme is marketed for medical use but some users try it for spoilers. In our evaluation, it lacks the weather resistance and shear strength needed for automotive exterior use. Owner reports indicate it may fail in rain or heat.
This tape is best for temporary indoor applications or for attaching lightweight trim. Do not use it for a spoiler that must withstand driving forces and outdoor exposure.
- Strong adhesion for medical devices
- Latex free
- Removes cleanly from most surfaces
Pros: Removes without residue; Gentle on paint
Cons: Not designed for heavy loads; Poor outdoor weather resistance
7. T-REX Double Sided Tape: All Weather
T-REX tape offers a balance of strength and weather resistance. In our research, it performs similarly to Gorilla tape but with slightly better heat tolerance. Owner feedback is mixed: some praise its holding power, while others note residue when removed.
This tape is a decent middle ground for spoilers that are not too heavy. However, if you want easy removal without residue, look for a tape specifically designed for that.
- Durable acrylic foam construction
- Works in extreme temperatures from -40F to 200F
- Holds up to 20 pounds per square inch
Pros: Good temperature range; Strong hold for moderate spoilers
Cons: May leave residue on removal; Thickness can be visible on some spoilers
Frequently Asked Questions
How do I prepare the surface for double sided tape on a spoiler?
Clean the area with isopropyl alcohol to remove wax, grease, and dirt. Make sure the surface is dry and at least 50F. For best adhesion, use a primer if recommended by the tape manufacturer.
Can double sided tape hold a spoiler at highway speeds?
Yes, if you use a high strength tape like 3M VHB or Tesa 4965 and apply it correctly. The tape must cover enough surface area and the spoiler should not be excessively heavy or large.
How long does double sided tape last on a spoiler?
Depending on the tape and environment, it can last several years. Premium acrylic foam tapes are UV and moisture resistant and can outlast the car if applied properly. Lower quality tapes may degrade in 6-12 months.
Will double sided tape damage my car's paint?
Most automotive grade tapes are designed to be removable without damage if removed carefully. However, if left on for years or exposed to heat, the adhesive may bond strongly and cause paint peeling when removed. Using a heat gun or adhesive remover can help.
What thickness of tape should I use for a spoiler?
Thicker tapes (0.045 to 0.06 inch) are better for filling gaps and conforming to curved surfaces. Thinner tapes (0.02 inch) work best when the spoiler sits flush against the trunk. Choose based on the fit of your spoiler.
Our Verdict
Our top pick is the 3M VHB 5952 for its unmatched strength and durability. For a more budget friendly option with good performance, the Gorilla Heavy Duty Double Sided Mounting Tape is a strong runner up.
