Well that or adding extra layers. Like i said kevlar has 20% the stength of cabon but takes a beating much better so it makes a good outer layer...... wait no were still talking about fiberglass right? yeah all i know is that the tube i posted a pic of is now chipped. The lesson: don't hit them with hammers.
