First I was wondering if there is a good way to fix fairings with cracked/scraped surfaces? Is there like an epoxy or something that will adhere so you can sand it smooth again? And is there a good website to buy unpainted lower cowling.

 

I've repaired loads of fairings with fiberglass and body filler. You can get all the stuff you need from Wal-Mart or Auto Zone or something. You can fill in most anything with Bondo (body filler).
