We performed an emergency repair on a trillium
when, as they drove into a fibreglass event the door fell off (really, this is true).
Our repair started by removing the screws and cleaning out the holes, then we mixed up some epoxy and put it into the holes in an attempt to stabilize and repair the embedded wood. The next step was to pack the hole with epoxy putty, after that set we re-drilled the holes and remounted the hinges.
This was several years ago and last summer the door was still working great.
