I had one on my S2000 and I won't put another one on any car. It's a good idea and works well for some peoplebut........in my case, I hit some rocks on the highway that cut right through the clear bra and scratched the paint underneath. After weighing the pros and cons (discoloration, cost) I decided I wouldn't put another one on. I've used regular OEM bras on previous cars and they worked better for me and stopped more damage. It's a pain for some people to regularly remove the thing to clear off debris or remove it when it gets wet but it wasn't an issue for me. My clearbra cost me $700-800 to get everything done. I could have the front of the car repainted for that (and did).
I learned the hard way that any of the mfr's that produce clearbras, well an OEM bra is thicker and protects better, just doesn't look as good. If the rocks are sharp they'll go right through that clearbra.

 

I think the point of the clearbra is to minimize damage and make the car look as good as possible at the same time. Sure I may need to repaint after 4 or 5 years when I sell the car, but that is better than repainting 3 times in 4 year to that I can enjoy the car while I have it.

 

Appt is for tomorrow morning. Having last minute indecision, but still a GO!

 

Deane; this is a good example of how it seems most people's clear bra experience goes (well, at least in my experience with cars that have clear bras); in general the bra does not crack, peel, or fade if applied properly however the paint underneath will fade less quickly than the rest of the paint on the car if it isn't regularly sealed (which of course most cars aren't). In general the quality of a clear bra comes down to the installer and to a lesser extent the material.

I personally recommend them, but I have a sort of hyper exaggerated experience with paint chips.
