Bandai Mr Mark Setter 40ml MS232 Gunze GSI Creos Paint Supply Tool Jar Bottle Liquid

Use Mr. Mark Softer and Mr. Mark Setter to apply dry transfer decals.

This not only softens decals but also sticks with an adhesive component. 

Apply a small amount to the position where the decal is to be stuck. Wait for a minute or so and press the decal lightly with a cloth, swab or the like to stick it.
