Balance of PerformanceDynatron™ Dyna Hair® reinforced body filler provides a balance of performance and economy when repairing splits, cracks or rust holes in automotive bodies. Reinforced with long strand fiberglass, this filler creates waterproof repairs that are twice the strength of ordinary body fillers. Our two component polyester compound applies easily and creates a smooth, professional quality repair. This filler is produced with the highest quality resins, talc and microspheres. Dynalite has become an industry standard because it combines ease of use, faster working properties and top notch results.Automotive body technicians rely on our filler for its good adhesion, consistent quality and compatibility with most paints. It combines spreading, easy mixing, good featheredging, and non separating properties into one filler.Using Dynatron™ Dynalite™ Light Weight Body Filler is as easy as this simple 6 step process:1. Clean the repair area using soap and water followed by a wax & grease remover/surface cleaner. Sand the surface as needed with grade P40 to P80 3M™ abrasive.Note: If grinding is required use a grade 50 3M™ grinding disc, blow off the sanding dust with clean dry air. If repairing galvanized steel, e coat, primed/ painted surfaces or aluminum, sand with grade P80 3M™ abrasive to remove the paint/primer. Blow off with clean dry compressed air and re clean the surface using a clean paper or cloth towel and a wax & grease remover/surface cleaner.2. Apply the required amount of body filler to a clean mixing surface. (Do not use discarded cardboard as a mixing surface as contamination may occur.) The correct hardener to filler ratio = 3 inch diameter circle 1/2 inch thick of filler to a 3 inch strip of cream hardener.3. Mix the body filler and cream hardener thoroughly, to a uniform color. Gel time/setting time is approximately 3-5 minutes @ 75°F (24°C) using 2% hardener as prescribed. Spread the filler on the mixing board, being sure to break any air bubbles that were introduced during mixing.4. Apply a thin layer using firm pressure to ensure maximum adhesion being sure to “wet out” the surface completely. Apply additional filler in layers, building up the damaged area higher than the surrounding surface. Maximum filler thickness should not exceed 1/4 inch. Allow curing time of 20 minutes.5. Sand the filler to the proper contour with 3M™ abrasives, using the following recommended grade sequence: P40, P80, P180. Note: If more filler is needed blow off with clean dry compressed air and follow steps 2 through 6.6. Wait approximately 45 minutes before applying primer and paint, always follow your paint company’s recommended procedures.
