Hi new to the carbon skinning done a few parts in the past but only small items. Iv have just done a larger part and all went well until fitted back to the car. It looks and feels as if the resin has sunk and gone all waveie and not smooth to touch although the resin is still solid. They were also 2k clear coated after words aswell. And was plenty of coats applied so is built up nicely
I also did some mirror caps at the same time and they are still perfect and not gone like the other part at all.
The parts are fitted to the external of the car so I thought it may be to do with the heat of the weather but looking at the temp it should withstand it should be fine
If any one could shed some light on why it’s doing this that would be great as I’m baffled lol.
I have added a couple of pictures but it doesunt really show up as bad

Post cure means exposing the part to elevated temperatures for a period of time, eg. 60 degrees C for 16 hours.
It is fairly likely you don't have an oven to do the post cure in, so you can either get a set of 500W halogen work lights and position them on the parts for 8 hours over 2 days, or you can leave the car sitting out in direct sunlight for a few days. Trouble with leaving it in the sun is if it then gets hotter later in the year than it is now, then you will likely go over the resins temperature capabilities again and have to repeat the process. So it's always best to try and get the parts as close to the maximum Tg of the resin as you can.
