Hi,

Got my vacuum bagging kit and almost ready to start experiment of making moulds and parts to radio controlled planes. 

I do intend to make a mould like your air scoop in your videos. 
But I am not sure how to the part itself from epoxy, fiberglass and carbon. 

May I put on release agent 
Paint the mould 
Layer of epoxy brushed on
Put fiberglass and carbon in place with hands as good as possible and then put it into a bagging setup?

As above a 3 piece mould is likely to be best.  Probably one piece for the top recess, then one for each half would mean it should release ok as long as the bulges aren't too big. Maybe 4 pieces if the bulges look likely to mechanically lock with 3 parts.

The layup technique in principle is as simple as you described.  Being wet lay spend as much time as possible getting out any trapped air using a bristle roller. Less trapped air will mean a better cosmetic finish.
