Brush the scrape mark or indention vigorously with a steel brush to remove any loose splinters, chips or debris.
Scoop filler out of the container with a putty knife.
Smash the filler into the indentation with the tip of the putty knife. Use the flexibility of the knife to spread the filler as you bend and slide the end of the knife with the filler over the indentation.
Spread the filler over the indentation evenly. If you run out of filler, scoop out some more and continue until the indentation is full of filler.
Blend the edges of the filler out flat with the putty knife. Let the filler dry for 24 hours.
Apply more filler if there is any shrinkage of the filler.
