I've got about 12 or so flights on my Extra and have noticed a couple of small cracks appearing in the cowl. I don't know if I want to lay a bit of glass cloth on the interior of it or find a aftermarket fiberglass cowl to replace it. The cowl is made of fairly thin ABS and attached at 4 points - I've noticed it vibrating pretty good when I'm doing my run up on the ground. My question is do you think it is worth laying cloth inside to reinforce for cowl or just get a glass one and have it over with? I put a fair amount of time into painting the one I have now and would hate to have to do it again but I haven't heard many good things said about the cowls that are included with the kits.

Thanks much,
Dan
