I was given this idea from a guy a who has used this method and he said that it has lasted as long as he has had the arrows. Over a long period of time it may break down the arrow but I always need new arrows within a couple of years due to all thestump shooting I do and small game/varmit shooting I do. Carbons are more durable but they not unbreakable and they are just as easy to loose as any other material. but never the less I will monitor the arrows and make sure I post any sideeffectssilicon has on them.
