Should I Use Putty or Bondo for Cars?

[HenryAnn]

It is recommended to use putty for cars. Putty consists of A epoxy resin and B polyamide hardener. A common hardening method is to add more hardener when kneading the putty. The chemical method involves using ethylene glycol and acetic acid, but this only theoretically accelerates the curing process of this type of AB epoxy resin. Both putty and bondo are used for repairing models, as well as for creating modifications and custom parts. Before drying, they are used to adhere to the model. Once dried, they become hard. However, bondo is toxic, so it is not recommended unless absolutely necessary. Even when used, it should only be operated in a well-ventilated area while wearing a gas mask.
