I took off the "bra" that came on my used van I just purchased. The van is a 2006 and had minor scratches on the hood from the bra, but in general the paint under is in good condition. I might be willing to sell if you are interested.
Just took mine off to see what it looks like underneath. Notbad at all. I took a clay bar to it and got all the particles out of the paint then waxed the heck out of it and it looks perfect now in every light and angle. I think if you take care of it there will be no problems. I am planning on putting mine back on. Mine is an 06 with 25k miles and has had bra from build. In my case it saved the hood!
