The xylene will thin the silicone, but not to pourable constancy. It will also weaken the rubber somewhat.

Ill be working on another project with rocks in the near future Ill do another series on painting and attaching a mount.
It will be a wall mount Sauger over rocks attached by a fin.

that would be real cool.

The xylene is good to use to thin out the first coat if you are making something with extremely fine detail like the hair pattern on bison horns, which is what I make copies of occasionally.  You don't pour it on; you paint it on, then switch to straight silicone with the acrylic paint.  After several layers, it's plenty strong. 
Thanks again for the tips.  I can't wait to see the painting.

It can be done on fish heads. the only trick is making sure the skin is dry to the touch or at least a bit tacky.
but this is true with most silicone fish head molds.

Also for some items (such as bison horns) you'll want to use a releasing agent like syn-lube.   I use it all the time and it's a spray.

Well I just moulded a rock using this method then I went back and read the instructions.  ;D
Demoulding was a right bastard and now I know why. The rock I used had some quartz in it and the bloody silicone stuck to those bits (should of put a release on it :-[) But never mind I can patch any dodgy bits on the mould. I'll cast it tomorrow. Going to use it for a snake hide ;)

I just made a reproduction set of antlers of a average rack that my Grandpaw had killed.  I have to say that this method captured absolutely every detail and looks great.  I used smooth-on 320 for the casting.  The only thing I noticed was that the casting diameter of the horns were slightly smaller than the real horns, kind of like the silicone mold shrank a little.  It wasn't bad enough to hurt though.  What would keep the mold from shrinking like that?  I also had difficulty making the mothermold because I couldn't get anything to stick to the silicone.  I eventually gave up on the mothermold and simply created a wooden jig to hold the horns and its points all in place.  It worked pretty good, but set up time was a killer.
