My advice to anyone, based on personal experience and talking to others, is to avoid "clear bras" like the plague. I had one installed on my 4runner when new and what a nightmare. I went to a reputable place and the stuff start lifting ever so slightly along the edges in places and letting dirt underneath etc, which of course will create its own set of problems over time...
Even worse, when I decided to abandon it and take it off myself I noticed that the knob that installed it actually cut into the paint on my vehicle when they were "trimming" with a knife. They install as pre-cut kits but some cutting is needed. I was beyond pissed. Fortunately for me it was only cut through the paint on the front grill of the truck. I insisted that the place that did the work replace the entire grill with a new part from Toyota. They did so and I am happy now.
Like I said, they were a reputable place and did the right thing in the end, making me happy...
The other thing. Go into some dealerships and look at the install jobs on some cars. Almost every one I have looked at on different cars, some on the showroom floor, were already lifting and had some dirt under the edges.
My view --> Drive your vehicle, enjoy it, wash it, wax it, fix any chips you get with some of those available paint chips repair kits (which do an amazing job), and sleep well.
I am extremely anal about my vehicles, but at the end of the day it is just a vehicle. I do the best I can, within reason, to care for them and keep them a long time.
As for the fading. They claim that no fading occurs over time but this is BS. It will fade your paint differently in the area that is covered. Unfortunately people only find this out later when they get sick of it and want to remove it because of all the potentials hassles with such a product. Then you've got an even bigger problem on your hands...two tone paint that didn't come from the factory...
My 2 cents
