has anyone tried Sonu Baits Fibre Paste

has anyone tried Sonu Baits Fibre Paste, I took some out yesterday as per instruction did one cup of paste powder to one of water ended up with a pile of mush !!

Add water a bit at a time until it gets to the stage where it is the texture of pastry. Leave it a few minutes to stiffen. It's brilliant stuff, you can hook it or mould it round the hook. It will withstand casting a waggler without flying off. A mouse chewed my bag open and ate some of the powder, bet it's feeling constipated now...
They also sell it ready mixed in a tub.
