Yes, they work perfect, Glenn & yesterday, whilst in the local tackle shop, i brought a new glug from sonubaits called barbel & carp liquid enhancer, the flavour is hemp & spicy sausage, which you use to glug pellets, boillies, pastes, meat & also use it in groundbaits, this one is also pva friendly aswell.
I'll let you know how i get on with the above mentioned glug.
I used to use another one made by richworth, called meat amino, that one works well in floodwater, when i've glugged good old pork luncheon meat.
If you are planning on glugging boilies it would be worth investing in some pots to soak them in, you know the one's with the bait needle attached to the underneath of the lid.
Pellets, just glug them on the bank, when you want to use them.
Will.
