I usually use Smooth-On branded 20shore silicones for my mould making, but on a whim decided to add some ArtSil to my cart of resin recently to give it a try - especially because it now comes in a softer 28A shore (which is better suited to my needs).
I was very impressed with the flow of the silicone in its liquid state, and as such it has excellent air-release properties. Most of the larger bubbles had risen to the surface within a minute, and many of the smaller ones popped during pouring. I pressure-cast my moulds, so this isn't a major factor for me, but it is a nice quality of life feature.
I did have some minor cure-inhibition on against some of the resin 3D prints, but spraying the print with a thin layer of primer on my second attempt sorted that right out.
In terms of the silicone's appearance once cured, the listing name suggests it is 'clear'. I wouldn't agree with this, it's approximately the opacity of skim or diluted milk. I'd say it's somewhere in the realm of semi-opaque in a slab mould, and translucent in thin coats - which you can see in the picture attached. Though, I am comparing this to Smooth-On SortaClear and Dragonskin (it's close to Dragonskin). It can be easily tinted with mica powders so that you can quickly tell your moulds apart at a glance.

Next time I'm ordering from JR I will likely add some more of this to my cart while I'm at it.
