There is one problem that rears its ugly head with this method...cold cracks and separation. I did this same thing for a while, then I got a Blending Block.
After a few days of curing, if you rub your finger on the end of the bait where the color separation is, you will peel the baits into two pieces, one of each color. One way I found to help eliminate this is to get a pencil torch and run it close to the baits without touching them. This melts the plastic a little and helps the two colors adhere.
Hope this helps, the baits look great.
