I've read on this forum that beveling the edges on holes drilled in the gelcoat will help prevent spider cracking. Can someone explain why that is? I've drilled many holes in my gelcoat for various things but did not bevel any of the edges. I drilled in reverse so as not to chip the gelcoat but did not go back and bevel the edges afterwards, and am wondering if I should go back and do it.

Thanks,

Al
