The better the quality of the clear coat the less likely to yellow. Most nowadays cars have a good UV stable clearcoat and paint.
Any resin whether epoxy PE or VE will yellow at some point in time if it is exposed to the elements. Now, there are few good ones with very good UV additives added, so that coupled with a really good clearcoat should protect the CF very well.
The clearcoat used by top car manufacturers is really, really up there! None of the things you and I have mentioned, is used by the CF aftermarket manufacturers mainly because of the costs. The market is quite competitive so they need to keep the costs down to compete with lower quality products in the market, therefore they need to cut certain corners. There are some good quality stuff out there but it costs quite a lot and sometimes not even worth the effort.
