I bought Higgs' car about 6 years ago. It still retains that engine-bay roll bar. Whoever did it, did a good job. When I bought the car, there were no cracks, and I thought it would help prevent cracking. And it may have helped, but it has not kept it from happening. Right behind the driver's side gill there are some little cracks in the paint. None on the passenger side. My guess at this, is that with me usually being the only one in the car, somehow with the weight more on one side, it has slowly developed cracks over time. Again, a total guess, but I don't understand why it is only on that one side. And it's the only place that I've noticed they've appeared. Other than that, the paint has held up very well.
If anyone wants more pictures of the setup, let me know and I'll take some and post.
