1:72 72 Masks for Ki-21-Ib Sally (ICM)

The real subject

The Ki-21 was a Japanese twin-engine bomber that the Allies listed under the code name Sally. The Ib designation belongs to an early version of this series. For building a model the important thing is that the machine has extensive glazing, that is exactly the place where masking by hand takes the most time and where every edge that runs astray shows.

What the masks solve

A mask is a pre-cut shape that is stuck onto the surface, covers it during spraying and, once lifted off, leaves a sharp edge behind. Against tape stuck down by hand it saves time and above all holds its shape even on curved areas and in corners, where tape wrinkles. The extent of the set, that is which particular areas it covers, is stated by the manufacturer.

How to use the masks

• Stick them onto a clean, smooth and degreased surface, always before spraying, not once the paint has dried.
• Press the edges down with a blunt tool so that paint does not run under them.
• Apply the paint in several thin coats; a heavy coat creeps under and makes a step.
• Lift the mask off while the paint is freshly dry, not after several days.
• Wipe any adhesive residue away with a soft cloth, not with a solvent, which would fog the glazing.
• Keep the mask you have lifted off until the model is finished; it may come in useful for a repair.

Who the set is for

It will be appreciated by anyone building this type in 1:72 scale who does not want to spend an evening cutting tape. A set of masks is supplied; the kit, paints and glue are not included in the delivery, unless stated otherwise.
