The Mysterious Case of the Vanishing VHB Tape

When it comes to attaching spoilers or other automotive accessories, 3M's VHB (Vinyl-Hot-Bond) tape is often the go-to choice for its exceptional adhesion properties. However, I recently experienced a bizarre issue with this tape that left me scratching my head.

I was installing a CF M Performance spoiler on my vehicle using the recommended 3M VHB double-sided tape and Adhesion Promoter. Everything seemed to be going smoothly until I noticed a strange gap in the tape - three inches of it had seemingly disappeared! Despite applying the tape as one long, single piece, there was a noticeable gap that I couldn't explain.

To make matters more puzzling, when I tried to push some extra tape into the gap using a plastic razor, it didn't seem to want to budge. It's almost as if the tape had gotten stuck to something while I was setting it, pulling it back and leaving this mysterious void.

After further investigation, I realized that somehow the tape must have gotten stuck to something on the left side of the spoiler, about an inch in from the end. This anomaly led me to wonder if the adhesion promoter played a role in this unusual occurrence.

In my experience, using Adhesion Promoter alongside VHB tape is crucial for achieving optimal results. Without it, the adhesive properties of the tape might not be sufficient to ensure a strong bond. I typically use IPA or Panel Prep wipes to clean the surface before applying the tape, making sure that there's no wax or other substances that could interfere with bonding.

In this case, I was impressed by how well the Adhesion Promoter worked in conjunction with the VHB tape. Although the experience left me baffled, I'm glad to report that the final result looks fantastic, and the spoiler is securely attached.

For those looking to replicate my experience, I recommend purchasing the 3M 3614 Super Strength Molding Tape from a reputable supplier like Advanced Auto. Be sure to verify the authenticity of the product and ensure it's made in the USA, as some counterfeit products may be available on Amazon.

In conclusion, while the mysterious case of the vanishing VHB tape was an unexpected surprise, I'm confident that using 3M VHB double-sided tape and Adhesion Promoter will yield excellent results for your automotive projects. Just remember to follow proper application procedures and take necessary precautions to ensure a strong bond.
