This product is specifically designed for metal bodywork. Use a dedicated plastic repair compound for bumpers.
The filler must be mixed at a 98:2 ratio with the provided hardener.
You can sand the filler after 20 minutes; once sanded smooth, apply a suitable primer before your base coat and lacquer.
Mesh is only required if you are filling a hole of significant size to provide structural support.
Yes, once fully cured, it is moisture-resistant and suitable for exterior automotive applications when correctly painted over.
Use P80 grit paper for the initial shaping, then progress to finer grits for a smooth finish.
Check the mixing ratio and ensure the hardener was thoroughly incorporated. In colder temperatures, the cure time will extend significantly.
Avoid vigorous mixing; gently fold the hardener into the filler to prevent air bubbles from getting trapped in the paste.
Ensure the surface was thoroughly degreased and sanded to provide 'tooth' for adhesion before applying the filler.
To ensure a lasting repair, proper surface preparation is critical. Remove all loose rust and flaking paint using a wire brush or sandpaper, then thoroughly degrease the area with an automotive-grade degreaser. Mix the putty and hardener strictly at a 98:2 ratio, stirring carefully to avoid folding air into the mixture, which can cause pinholes. Store the product in a cool, dry place when not in use to maintain the integrity of the resin. The filler is fully compatible with most modern automotive primer and lacquer systems.
