I just bought some of this stuff http://www.tomps.com/shop/rapimould-rtv-silicone-rubber-500g-p-215.html
Never used this stuff before, as I have only ever tin cure stuff previously.
So am wondering what is the safest way to make a mold box?, I was going to use some paper cups, and either lego blocks or a plasticard mold box.
Are these going to be OK?
Also, whilst I am asking, I have 2 things that I am needing copies of, some resin boots and a resin torso and a whitemetal torso, are these OK to use as masters with this stuff?
As I am really unsure of what will inhibit the curing, I know onion and garlic will, but that's it.
Thanks for any info/advice.
