Mr. Mark Setter is an adhesive component which gives decals greater adhesion to plastic parts. It is much easier to affix decals to plastic model parts when the parts have a rough surface. First the area to which the decal will be affixed is painted and then the decal is applied. After any air bubbles are removed by pressing on the decal with a cotton swab apply a coating of Mr. Mark Setter and allow the area to dry. Because the decal now has a greater degree of adhesion adhesive silvering (the floating and shiny quality of the clear parts of decals) will be greatly reduced or eliminated. Decals can be firmly affixed to uneven surfaces. It is perfect even for poorly made decals. Decals will have greater adhesion if the painted surface is followed with a top coat.
