Small crack in frame and some rather pricey quotes left me thinking that I should just do it myself.

Super easy, just sand it down to existing fibre, slap on some epoxy and a carbon patch. Ideally use a vacuum bag but in lieu of that a freezer bag and duct tape as tight as you can to force that resin in to the fibre and make the patch as compact as possible. Then sand until smooth and paint it.

A few hours worth of tinkering and what looked like a disaster has been sorted at a cost of less than $50 in resin and fibre - yay!
