MicroGAFFER is identical to professional gaffer tape in all ways except the problematic ones: size and weight. Use it anywhere youd use standard-size gaffers tape: secure cabling and other equipment, make minor repairs, block out staging, label control boards, and more. It tears off easily and leaves almost no residue, just like gaffers tape (because thats what it is.)
The difference is, its so compact, you can buy several rolls and keep them wherever you need them. Keep one in your cars glove compartment; one in your backpack; one in your SLR camera bag (and each of your other gear bags); you can even keep one in your pocket. Now, when you find a problem on the set or location, your solution will be within arms reach - solve the problem and move on.
