Needing To Make A Master Copy

[🪦 killnskin ●]

up until now I've only ever made my masters with latex, and like the topic starter, I don't want to use it again, because of the shrinkage, and the loss of detail. but I had a question about this product, do you pore it into the mold and than coat this inside making a hollow copy, or do you fill up the mold completely? also How much would you recommend for mastering a normal sized head mask with neck, but no shoulders? would the 2 quarts option be enough?
