Clean the area, first of all, to be repaired with a leather cleaner
If you are having to recolour the area as well now is the time to use the leather prep to prep all the area, making this good to carry out any colouring that you will be doing
At this stage, you need to put in your sub patch if you going to fill a hole
If you are just repairing scratches, scuffs or cat scratches, skip the prep section and start applying the heavy filler to the areas needing repair
Apply in thin layers, it’s best to build up the layers of heavy filler, drying between each layer to ensure for a perfect repair
You can dry the filler with a hairdryer and this can be sanded down with sandpaper anything from 1200 grit to 320 grit depending on how much filler has been used and how bad the area was that’s being repaired
