Aside from what this guy in the video says you can also get your parts changing shape when cooking with pre pregs.

The new composite part with mixed materials like this will cure at 100C -130C but then when it cools down the fiberglass will try to shrink whereas the carbon has literally no shrinkage so the two materials are fighting each other and can warp the part.

For cosmetic carbon parts with no loads then it can be fine to wrap carbon on top of fiberglass with wet room temp resin systems.
