So I've decided to make my first project with carbon fiber a difficult one(not smart?). Ill post pictures as I progress and advice as to what I'm doing would be appreciated.

The idea is to make a mould that wraps around the edges as they can be seen while on the car.

The clay in the front of the light is to fill in the cosmetic groves that the carbon probably wont lay into, should I just fill them in with Gel-coat and sand them off the mould, or try to fill them in like I have now? The clay is hard to smooth out nice and ill probably have to sand anyway.

I would like to make this a repeatable process because I'm practicing on a used pair of lights first and if it comes out good Id like to do mine.

prep for mould making so far

id put the resin feed at the complicated light end of the mould (the top of the light if on the car) and the vac feed at the bottom.  In theory it shouldnt make much difference if you use the EC method of clamping off both ends as the resin should of travelled everywhere, but i like to have the complicated bit infused first as you can mess around a bit with resin flow etc early on in the infusion if its not going where you want etc.

With envelope bagging and putty you MUST sand the putty smooth as it WILL have small strands of fibreglass poking out and they WILL pop your bag giving you small leaks you cant find.

Ideally even seal the putty in with a resin so the surface is smooth and wont puncture bags.
