A recent wind storm blew part of a tree on the back of my TT in my yard. Fortunately, the only damage I can find is a chip in the fiberglass. Everything I read about repairing fiberglass says to repair it from the back side. I am wondering if this is the way it has to be done correctly or can something this small be done safely from the outside. I will try to attach pics. Any help will be greatly appreciated.
The Styrofoam is what's showing underneath. There is also spider webbing on either side.
