I've narrowed it down to these three:
https://angelusdirect.com/products/firered-paint
https://angelusdirect.com/products/brick-paint
https://angelusdirect.com/products/angelus-chili-red-paint
The first one looks like a good bet.
As you can see in the pics below, the leather on the left boot of my Super Duck S Girl SET013-A is peeling off at the ankle area.
What can I do and use to repair this damage?
