Hi, I think I'm nearly ready to start building up the mould for the jaw of my Alien project but I would like some advise.
Firstly I've decided to make a 2 part mould, I'm intending to brush the silicone on thinly first & then add thickener to it up build.
The jaw is made from Newplast clay which is apparently sulphur free.
I need to know if I need to use a sealer? & if its an acrylic sealer will acrylic aerosol car paint be ok? also Matt, satin or gloss finnish?
& lastly have I done ok preping the jaw for moulding? are the separation area's I've made going to work?
Pic's....
Sorry to ask so many questions but I've not done this before & I really cant afford to waste the silicon.
Many thanks in advance for any help
