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.

Good point re the shrinkage.

Most manufacturers supply pre preg glad woven 90,200,285,400gm just like pre preg
Lots of it you can get pigmented black as people either lie an claim it's carbon parts or like the range rover bumpers pictured a carbon cosmetic coat and the bulk in glass
No problems an they fit like a glove
