Masking tape has many more uses than simply masking areas to protect them from paint. It is in some cases even more useful than duct tape. It's my tape of choice for covering holes in my computer and changing my QWERTY keyboard into a Dvorak one.
Pros: (mostly compared to duct tape)
- Masking tape does not come out of hair. Trust me.
- You cannot make clothing out of masking tape.
- Masking tape is not waterproof.
* I have never seen non-beige masking tape, but I have been informed by a few noders that such variants do indeed exist.
