Colourless liquid for use on Solarfilm, Solarspan, metals and some other plastics as an etch primer. After drying it improves the adhesion of many iron-ons, adhesives and paints to the treated surface. Applied to Solarfilm before applying an overlapping piece of Solarfilm, the overlap seam will be stronger, it will resist the entry of fuel and its edges will not lift even after long use.
Apply Prymol with a small pad of cloth or tissue. Use enough to moisten the surface, then allow to dry for a few minutes. When spraying paint, mask off as normal, spray a thin coat of Prymol, allow to dry and spray the paint as normal.
