yeah i have read stories of the resin/finish yellowing over time. i hit it with some jet seal and wax as soon as i was done adjusting it. i dont daily my car and it sits in my garage 5/6 days a week so i hope it doesnt happen.
There are cheap carbon fiber hoods, and I don't think VIS is one of them.
I had one on a car I had, geez, 15 years ago? It was the best quality carbon fiber hood I have ever seen at that time. Lots of hoods out there with varying degrees of clear coat thickness, some have ripples in the layers, odd fitment, you guys get it. From what I remember VIS was the most expensive for my particular car, and lined up against the competition there was no comparison whatsoever.
If they still have the same quality standards as they did two decades ago, you cannot go wrong with VIS. Now, I would probably paint the top of that hood to be different, a little low key. Benefit is people think you are much more mature than you are going the extra mile to actually paint an aftermarket hood, and secondly everyone gets a nice surprise when you pop it too!
Kekekeke!
