Sometimes I do and is because my plastic wasn’t hot enough. If my tails are freshly poured I don’t use school to clean them. If my tails have been laying around for days I use alcohol to clean the oil off that the plastic has secreted. I get my plastic around 360 when shooting a body onto a tail. I make sure my injector is a little warm so that it doesn’t cool my plastic off. When I shoot I make sure I hold pressure. As you can see in the one pic I posted I stretched the bait twice it’s size and tail didn’t pull off.
