Polymer clay such as Fimo & Super Sculpey can be used for original sculpture or a base for your model horse customization. It is plastic-like in texture, almost rubbery. It does not dry out to air exposure and can be worked on for several months. It must be baked in the oven to cure. I do not recommend it for sculpting with model horses- as it is a little bit brittle once baked. I often use this clay as a base for medallions or miniatures within your stable setup. It comes in different colours that do not need to be painted once baked. You cannot use this clay to directly customize on your model, as Breyers will melt in the oven. 

Apoxie & Magic Sculpt is a 2-part resin curing clay. Once mixed, the product activates & has approximately a 1 hour working time. It dries in 24 hours to a solid, sand-able, drill-able, waterproof compound. This clay is imperative for model horse customizing and is industry standard. You can use it directly on your Breyer Model horse & smooth it out with water or isopropyl alcohol. 

Oil based clay such as Monster Clay is a type of product that never cures. It can be heated up in the microwave to a soft or liquid consistency. This can be used to create sculptures that can be worked on for many months at a time. The purpose of this clay is for professional use in terms of creating work that will be cast. Once molded in silicon, the original sculpture will be destroyed but the clay can continue to be reused. This is perfect for medallion sculpting with the intention of creating resin copies. 

In this part I go through the process of deconstructing the model using a Dremel to sand, cut & carve. Then I use a heat gun to reposition the plastic. 

In this part I go through the process of reconstructing the model into it's new pose. I use a combination of wire, super glue & blue painters tape. 

In the final part I document the entire process it takes to paint the model to the classic primitive dun coat colour of the Fjord.
