Ebay for the RTV dont know the life span yet
and the smoother the mold casting material the better result
as not only does it lq make the cast release better it also gives the cast a smooth finish if you use wood sand it as smooth as
you can get it then cover it in cling film this also aids the release
of the mold hope it helps.

Vinamold is great stuff to use. It comes as a solid, you heat it to turn it liquid, pour it and hey presto. No mixing ratios either, and if you have a bad one you can just heat it up and use it again.
Go for the red as it's a bit more rigid than the yellow.
Maragon arts and crafts is the place to go

The yellow is more rigid than the red. Same price, far cheaper than silicon considering that you can re-use it. Casting Plaster, Plaster-of-Paris, Moulding in Modroc, Alginate, Latex, Silicone, Craft Materials & Kits, Water- & Weather-Resistant Plasters, ...

I don't know how you heat yours, but be careful that you don't use direct hear it can cause a mess (so I believe
) if you are not careful. I use a pan with sand in it now and another pan inside that for the vinamold, I also use a thermometer so I know when it is nearly there.

Looking for some tips off you peeps on making silicon moulds, what and where do you get the silicon from and do they last a long time?
I missed your second question I use corian and glue it into position with double-sided tape, that way it is easy to take apart when you want to release your mould. You can see the last one I made here.
