Also does anybody know if it'll be ok to paint the clay (oil based) with Humbrol satin enamel while I'm at it?? will it work ok with a brush-on mould?? or am I likely to cause myself problems:confused
The only thing I think could happen is that the paint might pull off with the silicone when you are demoulding. I primed my T1 base prior to moulding and the silcone pulled some little bits of primer off and they transfered to the first couple of castings I made. No biggie really. Enamel might be different, but I just wonder if , as it's on oil based clay, big sections of the enamel might pull off with the mould. Still might not be much of a concern, but it's there.
Still looking fabulous too, Leigh

It will work. we use krylon crystal clear or matte spray. Watch using plastic cling wrap and paper towels during the matrix they will mar your smooth enamel surface. Use white trash bags instead to protect the sculpt during the clay up phase of your mold.
I just read something I missed. Your doing a brush up? The process I was describing is very technical vs a brush up. Matrix or case molds are self made containers that hold the silicone against your shape. They use far more silicone than a brush up but last many years. Sorry for the confusion.
