Good but not dull, and not really canvas.

The roll is impressive: 11 cm wide, you have to think about when starting with nomadic adventure! It takes a good place in the bag!
I ordered to make emergency repairs on an inflatable kayak. It sticks as well as my previous web roll of another brand, tears indeed with the teeth, making a straight tear and clean, but it is not the "fabric" as the name indicates you the.
This tape is so plastic, close enough moreover, armed with a plastic mesh end slipped between his two films, black and sticky.
In other words, no flexibility, not to mention the spread and deform like a real scotch cloth "canvas".
Also note, it shines more in real life than on the photo, it's nothing dull: not terrible in wildlife photography or geocaching, to camouflage. The slightest light reflection, bling, it hangs.
Apart from that, no doubt, it sticks well, although I did not test in real water on the kayak (commissioned in December, brrr ....). but I do not expect miracles, because experience proves that water ruin in a few weeks, as robust scotch they are. So do not expect to use it not as a patch on an inflatable boat or buoy leaking, but tell you it's the troubleshooting for last few days. To really repair a boat / buoy, you need a patch and special adhesives that are very expensive.
