    The "plastic" will shrink as it cools and can cause an air pocket or you are trapping a bubble in the mould
    It may be worth making an air escape vent in the mould,

    I have found that heating the plastic too much in the microwave causes a fine layer of air bubbles to form on the surface - which then transfer to the lures. This often happens when i am repeatedly melting the same plastic in a jug in-between pours to keep it molten. Perhaps try a little less time in the microwave (i assume that is how you are melting?) so that the plastic doesn't get so hot. It works for me anyway :)

    hi,what mould is that please?
    do you think you could rig it on just a plain hook 6/0,rather than a jig head for wrecking or will it spin?
