In the past, Mr. Mark Softer was used as the first choice to soften decals. However, now 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 part where the parts either have a rough or irregular surface.
How to Use Mr. Mark Setter
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, a coating of Mr. Mark Setter is applied and allowed 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, and decals can be firmly affixed to uneven surfaces. It is perfect even for poorly made decals from Eastern European models. Decals will have greater adhesion if the painted surface is first prepared with a gloss finish.
