I remember some years back that you could buy the equipment, molds and liquid plastic to make your own plastic worms/grubs from several vendors such as Bass Pro and Cabela's.  However, I was looking through the current catalogs from Bass Pro and Cabela's and notice that none of this seems to be available anymore.  Did they stop carrying it?  Can you still get these items anywhere, anymore?

There are several companies that carry molds, PU plastic, metal flake, dyes, even fluored salt to make your baits. How much yo ' 're going to spend depends greatly on what you plan to pour and the quality of the molds you purchase, resin molds are pretty inexpensive but baits aren 't as "pretty" as the ones made in aluminum molds.
