Repair basics:
Many of the bodies are damaged over time and require repair. Some are in better shape than others.
Due to the age of the plastic involved, great care must be taken not to increase the damage. A femlin I had needed repair because her head had fallen off shortly after I received it. So, additional damage was not really a concern.
Epoxy in liquid or putty clay form seems to work best for repairs. Putty clays include Aves, Magic Sculpt and Miliput.
As mentioned earlier, these repairs should only be attempted by those with serious modeling skills. Unskilled attempts may lead to irreversible damage.
