How much paint do I need?

[erebus]

I will be painting my face, and my fiance's face for halloween. About how much airbrush makeup will I need to buy? Will 1 oz do it? I found a 1 oz bottle of mehron on ebay for $5 and $5 shipping. Is that a good price for mehron or is mehron a bad makeup? Also, I saw that I should use 10-15 psi to paint on skin, is that the same psi for a gravity fed and a siphoned fed?

Are you painting both your faces only 1 solid color? 1 oz will be more than enough! I use 15-30psi on skin regularly.

I ended up getting a 1 oz jar of Mehron on ebay for pretty cheap. It is the liquid makeup so will I need to thin it before I use it? If so, what can I thin it with and about how much? Also, I will probably use it when I get it to see how it looks, then I will paint my face for out party, then both of our faces for halloween. So will 1 oz do 4 faces or should I go a head and order more just to be prepared?
