I put the carbon fiber when the resin was already dry and lightly marking the fingerprint. After that I laminated and then put it in the vacuum bag. The problems were as follows: - dry areas on the carbon behind the surface resin coat that I made to replace the gelcoat - Corners with air bubbles, even putting carbon with tacky resin. What should I have done wrong?

You need to thoroughly soak the carbon otherwise this can happen. On the gel coat issue, why are you adding one? If the mould is shiny and you are using a chemical release agent, such as Easy Lease, then the carbon will come out shiny. Brush on a light coat of resin on to the mould surface prior to the first layer of carbon is all you need to do, IMO. To avoid pinholes, air bubbles and bridges. And yes, the resin as gelcoat was practically dry glued lightly to place the carbon in the mold. But even using the resin as "gelcoat" to have the tacky, happened to have bridges and air bubbles, I believe carbon fiber should not have lifted.
