Poly-Flex is a flexible polyester glazing putty designed for spot filling and skim coating over repair areas on flexible bumpers and plastic parts. This car putty has flowable viscosity that is ideal for filling minor imperfections, such as sand scratches, nicks, dings and gouges. This finishing putty may also be used to skim coat over repair areas or large surface areas that have the original paint still intact. Blue cream hardener included. For best results, clean and degrease the entire panel to be repaired with soap and water, followed by a mild cleaning solvent. Thoroughly dry the surface before repairing. Use 80-180 grit to remove or scuff the paint and featheredge. Place the desired amount of material on a clean, non-fibrous surface. Knead the cream hardener before use. Measure hardener 2% by weight (add a ribbon of cream hardener from edge to edge across the center of a 4” (10 cm) diameter puddle. Puddles larger than 4” in diameter will require additional hardener. Mix thoroughly until uniform color is achieved. Approximate setting time is 5-6 minutes at 72°F (22°C) Spread a thin layer of mixed material over surface using firm pressure. Apply additional layers to build material slightly higher than the surface to allow for sanding to desired contour. NOTE: Do not apply over new or uncured coatings. Avoid thick heavy applications. Sand to contour with 180 grit sandpaper. Final sand with 180 grit followed by 220-320 grit if desired. Apply 2K polyester, 2K urethane, 2K epoxy, or 1K primer to manufacturer’s recommendations.
