Strength in Numbers
One little mushroom won't accomplish much in this world, but pair him up with a few hundred of his friends and he becomes nearly unstoppable. Teamwork, that's the idea behind the design on the 3M Dual Lock Reclosable Fastener TB3550. When joined together, these unique, mushroom-shaped stems combine to interlock with one another, generating five times the closure strength of typical hook and loop fasteners while maintaining the ability to easily peel-apart for quick access.
3M Dual Lock TB3550 Reclosable Fastener contains approximately 250 mushroom-shaped head stems per square inch. When two pieces of Dual Lock are pressed together the stems flex and the mushroom heads slide past each other. After mating, the stem snaps back into its original position, interlocking with the opposing heads with an audible snap that signals the fastener is engaged. This system can be opened and closed 1,000 times while maintaining 50% of the original tensile strength.
No Drilling, Screwing, Tightening, or Complex Installation
3M Dual Lock TB3550 uses an acrylic adhesive that bonds well to a variety of high medium surface energy materials, including some plastics, metal, glass and painted surfaces. This ensures a quick and easy installation without the use of mechanical attachment processes. The adhesive sticks quickly and reaches full strength after 72 hours. Once bonded the interlocked, mushroom-shaped stems provide an attachment that holds as well as screws or rivets, yet separates easily for access.
Versatile, Durable and Invisible
There's no limit to the number of uses for 3M Dual Lock fasteners. The stems, mushroom tops, and film backing are constructed of clear polypropylene, and the polyolefin backing resist common solvents and alkaline solutions, making them ideal for a variety of purposes and environments. The fastener is recommended for use at temperatures ranging from -20°F/-29°C to 200°F/93”C. Hidden from view when attached, these fasteners provide a clean, unbroken surface, and stay strong through more than 1,000 open-close cycles.
Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. They are ideal for both indoor and outdoor applications including: attaching signs, cushions, enclosure and access panels, banners, doors, adjustable shelving, vehicle ceiling panels, furniture seats and backs, and much more.
From the Manufacturer

This Dual Lock product uses durable acrylic adhesive to bond strongly to metals, glass, some plastics and painted surfaces. The adhesive sticks quickly and reaches full strength after 72 hours.

No drilling, screwing, tightening, or complex processes
When two pieces of Dual Lock fastener are pressed together, the stems flex and the mushroom heads slide past each other. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. The audible snap signals the fastener is engaged. The attachment formed may be as effective as screws or rivets, but will peel apart for repositioning.

I thought that $2.14 a foot was a bit high, but with Amazon Prime it was doable.
What you actually receive is 20 feet. The package contains two 10 foot rolls. That makes the price per foot $1.07 which is an excellent price.
Notice the picture does show two rolls. Each of those rolls is 10 feet, not 5 feet like you might expect, given the description.
If you don't know what dual lock is think of the strips they give you with your ez-pass for mounting on the window.
The adhesive is great but here are a few tips.
Clean the surfaces thoroughly. I suggest some rubbing alcohol clean both surfaces and let it dry. This is common sense but many people forget to do this.
Make sure the surfaces are flat. if its textured you can use a little sandpaper. be sure its not a visible area.
Use a lighter and heat up the adhesive just slightly. Do not scorch the the adhesive, just a few quick passes makes it slightly more pliable and much more sticky. This is especially important if it is near freezing.
On a surface where you are having particular difficulty getting any type of adhesive to adhere, a small dot of crazy glue in the center will do the trick. Just make sure its on a surface you wouldn't mind leaving a mark if you had to pull it off.
