I was having a bit of a sort out of our Gunge stock and have quite a bit of Carboxy Methyl Cellulose to clear. 950g should make around 50 to 60 litres of a reasonably thick gunge. It takes a bit of mixing, ideally an electric mixer or drill with mixer attachment.
For any of you looking for powder paint for colouring we have a huge quantity available. We can do the 9kg tubs at £20 including postage or can arrange collection for larger orders.
