Installer's Pen is filled with 3M™ Primer 94 adhesive promoter. It increases the adhesive strength of vinyl.

Apply to spots that have the potential to lift, such as the edges of a wrap or a recessed body panel. In these areas, the film has the potential to pop out without some help. Adhesive promoter is also helpful when applying paint protection film (PPF). It helps secure edges like around and under hoods as well into wheel wells.

The pen format has two advantages. It is much more precise than a rag or brush. It applies the 3M™ Primer 94 exactly where you want it and exactly as much as you want. It is also faster and easier since the pen is ready to go whenever you are.
