3M Products Single Step Primers

3M Products introduces the most user-friendly primer on the market today! Single Step primers promote urethane adhesion to automotive glass, paint primers, encapsulated parts, and pre-applied adhesive systems, while protecting the urethane from harmful ultraviolet rays. This primer can also be used to touch-up scratches on the pinchweld and prevent corrosion from occurring over time. 3M Products Single Step primers do not need an activator; they do, however, need to be used within one week of being opened, as moisture and other contaminates can cause the primer to become less effective.
