I just spray my carbons and aluninums with silicone. In foam targets the shafts melt the target material. Gold Tip tells me to spray the shaft with Pam. Anyways, there were times when shooting too close the the target, I had to tip the target over and stand on it the pull the arrows out. Silicone makes a huge difference. If I had to guess Planter's aluninum shafts are heavier so they melt more foam.
