20-820 One-step 2K Polyester Putty Incl.Hardener

Super-light 2K polyester one-step putty reinforced with glass fiber. Its creamy consistency lets you build in 2–4 mm layers and achieve fine sanding with P120–P150 grits. Provides adequate hardness for automotive coatings and reduces ridges between the putty and repaired surface. Can be applied directly as an underfiller before primer. Supplied with hardener for reliable two-component curing.
