Lure Makers Supplies

Sodium Benzoate
Stops bait from decomposing after reaching desired stage
of taint. Use 2 tablespoons per pint or 1 cup per gallon to
preserve fresh or aged meat or fish baits.

Glycerine Oil (High Grade)
Glycerine is not a preservative, it is used to stabilize & blend.
Also used as an antifreeze when mixed with glands. It is mixed
with urine to add body, prevent evaporation when exposed
to the air, and prevent freezing.

Propylene Glycol
Similar uses as Glycerine Oil. Used for anti-freeze in urines
and as tincturing ingredient. 

 
Methyl Paraben
Superior preservative. Best at keeping the true odor of meat, 
fish & glands. Methyl Paraben is hard to find and even harder 
to find at a price that is not prohibitive. This is a superior 
product at a real value. Use at the same ratio 
as Sodium Benzoate.

Zinc Valerate Powder
Used in the same manner as Sodium Benzoate by lure and bait
makers, except it's main function is to stimulate odors during
the aging process and stabilize them when in use.
Use 1/2 teaspoon to a gallon of bait.
