I was very worried that this product wouldn't work. Like terrified. I had visions that my solar panel would fly off the roof of my vehicle and come crashing down on the highway. However, other people had attested that this stuff worked great and they never had any issues.
I am happy to say I have travelled about 3,500 miles and counting with this tape holding my solar panel to the roof of my car and I have not had any issues at all. I would say it holds up well and you can rest easy knowing that this adhesive bond tape will likely get the job done. If you are installing a solar panel on the roof of your car, this is a much quicker and efficient way to install without wrecking the roof. I would order this product again.
tissue tape= ripped off at 35mph after proper applying to my helmet...(72 hour dry time)
This tape/VHB tape = Stayed on my helmet rock solid with a 16 hour overnight dry time. Not a single vibration up to 65 mph (road limits)
This tape STICKS forever and if you missed a spot you can see it and note where its not stuck properly so you can peel and reapply properly.
the only way to mess it up is to not stick properly. Therefore this tape works perfectly.
Currently testing it with a 25 pound weight being held to a wall with it (multiple small pads due to surface size) still going strong three days later. :D
Overall. 5 stars or a 10/10
Does what it needs. works flawlessly. DOES NOT leave a nasty sticky residue when taken off during the dry period (miss placed a mount took it off and reapplied. worked flawlessly afterwards and cleaned nicely.)
Update.... Jan 13, 2015.
The original tape I used in May 2014 on my motorcycle helmet camera is still holding strong. Haven't changed it out yet. It has been soaked with rain and had the sun beat down on it in over 100 degree (f) days.
I'd tried hot glue gun glue (melted in hot sun light), normal double sided tape (not strong enough), and gorilla glue (just did not hold).
This VHB tape is like magic and does the job perfectly . You can even peel it off if you decide at a later date.
I've used this tape for other things too, like attaching IR receivers to the outside of my cabinet, and as cable tidy to keep cable against a wall.
These VHB tapes a very finicky as to what and where they will hold. Get it right and you'll have a fierce connection. Get it wrong and it pulls right off.
