Experience with the Flexil/Vinamold/Gelflex hot melt vinyl rubber?
Does anyone have any experience with this Flexil hot melt rubber stuff I've seen about. It's a vinyl rubber that you melt in a pot around 170 degrees and then pour it over masters and formers to create moulds like you would with RTV silicone (except quite hot). The rubber can be remelted which is a benefit over silicone, but does anyone know of reasons why silicone is better for making moulds with (other than the master possibly melting).

Incidentally, CFS is also a good place to buy pretty much all casting and moulding materials if you're in the UK at somewhat reasonable prices :-)
