Some care has to be taken in deciding which plastics to re-melt. Gulp, Trigger-X, Powerbait, Exude are all common plastics that one should not be melting for re-casting baits. The Gulp and Trigger-X products have a water-based product and that alone can yield some very nasty blow-ups while melting. Secondarily all of those mentioned contain scent components that noxious when the plastic is re-melted. There are other scented products in the market-place that can give off some very nasty fumes and odors too. While the respirator might protect a person doing the immediate re-melting, those fumes travel in open air and can affect others not so lucky to be wearing the device.
Whether re-melting is on your schedule or not, all plastics users should carry an old coffee can with a lid to toss used plastics into so they can get disposed of properly once home.
Open-pour molds can be made from RTV silicone or even plaster-of-paris using new plastic baits as the forms. Using the re-melted old baits is a prudent way to get “new” baits in some un-real colors. Of course the injectable molds shown here in Skimpy’s video produce higher quality baits. Skimpy does a great job with his baits.
