with. To save time, we will discuss only two different types here; polyurethanes*
and silicones*. Within these two groups there are a wide variety to choose
from. In order to make your choice properly, there are many factors to consider:
flexibility* working time* cure time* viscosity* and of course price*. In addition, one should consider several basic questions; What your original is made of and does it have any under-cuts?
