right well to start i normaly only use rvt but silicone is silicone i take it you have got thickso as well to thicken the silicone well with the rtv i start with just usesing the silicone with out the thicksotopic then brush two layers on the sculpt for the print coat then after the 2 layers are dry i then mix more silicone but with the thickso i only use a teaspone of this in all to help you out your best bet is to watch the videos on youtube there helped me out a lot

You can, but why do you want to? What if your sculpt takes a knock while waiting for the mother mold? The silicone won't protect it, and now your sculpt is damaged and the mold ruined.

So no, while there is no reason not to put the silicone on now from a technical, "will the silicone damage the sculpt or vice versa" point of view, I personally would wait until you have all the materials at hand to do it in one go. What are you molding?

oh.. ok, thank you :D

and as far as what i'm molding, it's an upper body "armor" that i've been working on for about 2.5-3 months and i'm finally in site of the finish line
