yeah the techniques are the same for most FRP products, eg carbon, glass, aramid(kevlar) etc. Wet lay ups with carbon are a bit gay, but you can get a pretty good finish from it if you're careful (experience helps!). Me and my girlfriend did a repair on the carbon plenum for the fsae car by just doing a wet lay up on it, came out pretty sweet (didn't survive too long though, damaged in shipping on way back from Aus)
Most people use epoxy resin with carbon, but you don't have to. The easiest method to ensure good wetting out is to soak the cloth in resin first, usually by putting a piece of plastic sheet on a bench, lay the cloth onto it, then pour resin on and spread it around with a spatula (plastic bog applicators are good), then pick up the cloth and apply it. Don't do too many layers at once if you're a noob because you may struggle to get them all properly wetted out with no air bubbles between them
