Ok after seeing and hearing about several fenders breaking loose and causing problems on the bike and the rider I pulled off my front fender. I noticed stress cracks already. And this after 15-20 miles of riding. So here is my fix, hopefully. I got a fiberglass repair kit and laid up 4 layers in resin about 6 inches around the problem area front and back, and out to the ends of the fenders. I simply used tape on the chrome side to keep the resin from seeping through. I'll let you know if it works. Right now they seem extremely strong.
