What's a good filler material in AU we can get to fix carbon wings tiny reef bites? Does spraying with primer actually work long term? Anyone tried plumbers putty aka epoxy putty ?

I use west coast systems epoxy and cut up fine bits of carbon on larger repairs. On small ones I use 413 added to the epoxy then sand smooth. Worked well so far.
I use Epifill from International and add a tiny bit of black epoxy tint. Comes in small tubes and is easy to use and sands perfectly. Get it from marine shops. I've tried adding chopped carbon fibre to it but for small gouges or nicks best on its own.
Super glue and powdered graphite for gouges and scratches. Basically the same colour but a little softer so easy to sand smooth.; best glue is from a hobby store (used for building model planes). Powdered graphite from a hardware store (used for locks)
I use epoxy resin. Clean the damaged area and apply a small amount of resin. The trick is that before the resin goes fully hard, use a razor blade to cut the excess resin off. Makes sanding really easy and results in a really durable repair
I use solar cure resin fore small dings on the surfaces. Edges need epoxy and some sort of filler. I do ding repairs, so I have colloidal silica around for trailing edges. Polyester solar resin wet rubs smoother than epoxy. I have made a few foil wings, and leading edges can be affected by the roughness of q cell or some putties. I once added a whole leading edge of q cell filler to alter a foil profile, it destroyed the laminar flow. I faired and wet rubbed it with resin and it transformed it incredibly. The hardest thing is sanding a small ding without going through to the laminate. Panel (or body) files work well....
