meguiars mirror glaze release wax
There are others but I use this.
Chris, seeing your post, i went along to see my Fibre Glass moulder tenant to ask his advice, and he suggested a product, the tin of which I have taken a photo of and will try to attach.
And whats more, he has given me the tin with a small amount in, which I shall bring to Uncle Phil's on Saturday.
Are you moulding or releasing from a mould?
What finish are you after?
What finish has the pattern/mould got?
Honey wax or PVA, or both depending on the application.
Thanks Craig, Paul, Robin,Quote:

I have already made a 'first effort' which I now know I can perfect.
In the process of that, I used the remnants of an old 'Back to Black' aerosol, which worked to a degree, but not as good as it could have been.
Robin, that's kind of you, thanks.
Sounds like a one off use then Chris?
PVA has never failed for me.
I'm no expert but I think waxes are more for moulds you are going to use repeatedly, where you can build up a decent thickness of release agent to a high finish.
PVA has been quite forgiving for me.
Bear in mind though it's a different PVA than the White glue used for woodwork. Using that might have the opposite effect desired!
It's blue and sort of smells a bit like french polish.

Thanks to John D., Craig and Paul.
I used Robin's tin of wax and some PVA (is it always blue coloured?).
Anyhow, it worked, and I've got a much much better grp side of the press tool this time.
'Will update at the next stage.
