[Tool Name:] Masking Tape [Why You Need It:] 
Provides a clean, sharp delineation between colors. Essential if airbrushing or spray painting. Use the tan stuff for large area masking, but don't use it for the edge. Use the blue tape for the edge. It works much better. Very thin strips can be cut from the blue, or purchased separately for curves and details.
