body cracks stress

[melliott]

I have an a&c bought 2 months ago with 400 miles on it was flawless. drove 300 miles developed cracks around windshield posts hood corners at rear. around corner of louvers, and around roll bar. I checked clearances don't find anything hitting. I did find no rubber between frame rails and body. I wondered if this could be problem. a new crack is seen everytime I drive it, even babying it in and out of parking lots etc. I want to fix problem before recoating or painting. I also wondered about adding fiberglass stiffening under body in areas where cracks developing to add stiffness. Any help or suggestions appreciated
