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.
