With some of the masking kits from Orbital Drydock and HDA Modelworx, entire sections of masks are transferred from the sheet to the model with "transfer tape" - it's essentially a piece of clear low tack tape the size of a standard sheet of paper.
The process has you cut out a section of the mask, which is then "weeded", meaning the undesired bits and pieces are pulled away and discarded. A similarly sized piece of transfer tape is burnished over the mask, allowing for it to be lifted in one piece, then the mask is positioned. Once satisfied that everything is good to go, the mask is burnished into place (Orbital provides a squeegee tool for this) and the tape is carefully rolled back over itself, leaving your mask ready to spray.
The system takes a little practice to get used to, but once you figure out things, it makes big masking jobs go fairly quickly.
