look up smooth-on on the net the oomoo25 is the best deal ive found get the 22 lb kit for around 150 dollars delivered.you will get around 40 molds depending on the size of the mold.you could probably get more molds than that but i make mine a lil thick.this siliconeneeds no vacum and it releases from the frame with no problems glue you master down to bottom of mold box,you cant push it down.cure time is 90 minutes i let mine sit for 3 hours and its never gummy on the edges make your frames out of the cheep strip wood at local harware store alot of guys use baking pans and tupperware but theres alot of wasted space which in turns wastes alot of the silicone my email is shanescustombaits@yahoo.com message me if you need help.
