Steve....I shoot up a ton of baits just for tail stock. And by tons I mean I'll sit all day shooting just chartreuse baits, say paddletails, until I have three or four thousand done. Then I cut the baits in half, making sure what I need for tails later on is left cut long. I bag the tail sections in 1 gallon bags for future use. I leave the tail sections long because these will exude oil in storage. Instead of having to wash them all in alcohol prior to using them to get that oil off, I simply cut them to the length I want, discard the buttons from the trim, and place thenm in the mold and shoot away. The fresh cut exposes oil-free surface plastic to assure a solid weld, plus the slight amount of oil remaining on the tail portion acts as a lubricant for getting testy tail buttons back into cavity areas where they'd normally balk without any lube used.
I make all NEW plastic for the tails and re-heat it one time during the injection process of tail making. All of the left-over plastic in the cups, sprues and trimmed bodies goes into gallon zip lock bags for re-melting later on...for other projects where I need a 4 ounce batch here or there. I don't use chartreuse, green chartreuse, fluorescent orange or fluorescent hot pink for anything but tails and make all of my tail stock the same way using those colors and keep all of my scraps as described.
The chartreuse you see here on these baits is simple. For an 8 ounce cup of plastic I add a baby aspirin sized ball of blue hi lite and a pea-sized ball of UV enhancer powder, stabilizer, 1 drop of X2 White, 2 drops of X2 Fluorescent green and 18 drops of Chartreuse X2.
