Description Mark Fit is a special solvent designed to soften your model decals which will allow you to apply them onto difficult to apply areas such as bumpy and curved surfaces, providing an improved finish to your scale model. The 40ml bottle contains a convenient brush for easy application. • Apply Mark Fit solvent to area where decal is to be positioned. • Place decal onto the area. • Slide decal into correct position by a wet finger. • Use a soft cloth or cotton swab to remove excess water and any air bubbles. • Apply Mark Fit over the decal again, and then use a soft cloth or cotton swab to conform it to the model’s surface. • Do not touch until decal dries completely.
