longevity of clear bra?

[rbensmithX3]

I assume you're talking about the 3M product. . .I bought a used X3 and the previous owner had this done at the dealership. I never really notice it and it covers every nook and cranny on the hood, mirrors, doors, etc. It has not peeled at all (2 years) and supposedly you can wax it/treat it like paint. My only issue is that there appears to be water spots on it at all times and bug marks do not come off easily. This is a small price to pay knowing there a no chips on the hood.
