You can fill big dents or scratches with this Polyester Tube Putty. The tube type putty allows you to take the liquid out of it as needed.
Directions to use
1. Remove the rust or cracks with the 150-grit sandpaper.
2. Take the same length of the fluid out of the both tubes (It should be 100 parts putty with 2 parts hardener), and mix them evenly with the included spatula. Afterwards, apply the mixed putty on the part being repaired.
3. The putty will harden for 1 hour. Polish with 320-grit and 600-grit sandpaper after the putty hardens.
