If you are a special makeup effects artist like me, you will most likely be bored by the calculations on how much silicone you should mix.
Here in this app you will find a simple solution.
Simply add the total amount of silicone you need to fill your mold.
Then enter how soft you want your silicone by typing how many percent (%) Polytek Deadner, PS-Comp Softner or Smooth-On Slacker you want to add to it.
And then the results are in your hand!!
