Making this part in CF, no mould

Hi, 

so I'm planning to make this part in CF. Plan was, coat it in a clear coat to get a smooth surface. Wax and use PVA release agent, then apply epoxy, and lay few layers of CF. (3 of 2/2 twill 400g)

Then extract the new part, and cut and do some gentle sanding with fine grit. Then, once its reasonably clean, apply a few layers of clear coat and sand those back as I hear sanding on laminating resin can go through easy. 

Any thoughts/advice?

Thanks

You may not even need any sealing coat as often the epoxy resins do not stick to these plastics. Maybe just wax but do a test on the back first.




Having said that though, it looks like way too much shape, detail and corners to do with 200g or any carbon and expect it to look good. Too hard!
