Can you use brush on latex to make a 2 part mold?

I have this brush on latex rubber mold solution that I got at the craft store. Is it possible to use this stuff to make a 2 part mold by pouring it, or will the two halfs of the mold just end up sticking to each other?Can you use brush on latex to make a 2 part mold?
Not sure what material you are trying to make the mold from, but assuming it is not porous, spray a coat of mold release on the part. then brush on a layer of latex. Following the directions, let it dry and re-coat as recommended. You will need to build the mold up so that it won't tear when you remove it, so you may need 6 to 10 coats, depending on the part size and complexity. Let the latex cure fully (or as recommend by the manufacturer) and remove the part.
