Is this also the way to go to make spoilers?

Definitely recommend going for infusion, and playing around with it a bit before attempting a bonnet. I think I jumped into it a bit quickly, expecting it to be as easy as the EC and other videos make it look. But there is a bit of a learning curve to it, I still haven't achieved a perfect finish straight out of the mold, but I'm getting there 

Vacuum assisted curing: vacuum bagging or vacuum infusion is best for the complex curves and shapes that may be in a hood. Just doing a wetlay without vacuum will most likely cause bridging on those complex curves. Also in an infusion setup you can use spray adhesive to make sure the carbon is laid in all of the curves. So, yes I believe you should buy or start building an infusion setup. Once you get it, start with small parts to get accustomed to the new process. 

Be sure to make sure you vacuum pump is appropriately sized to do the job.  My first attempt at resin infusion I used a 8cfm unit with low viscosity epoxy resin (adtech 820) and I pulled it across my 1mx1.5m test section in less than a min.  I wasn't prepared for that and ended up wrecking my first batch of parts.  Good luck and what type of car were you thinking about doing?
