We've been epoxying stuff together that wouldn't zip tie well - that lower fairing was in three pieces - and we're pretty familiar with fiberglassing - we built a boat a few years ago and learned how to do it for that project. Mostly this is just an artistic / philosophical decision; we want it to show its scars rather than erase the history, if that makes sense? That's why we're using pretty, colorful zip ties for the repairs.
Some of the mounting brackets and pins and stuff we will be recreating since zip ties won't necessarily work right in those locations. They're mostly going to be for the random cracks here and there.
