I'm surprised your dealer didn't try to sell you a clear bra, tint, sealant, etc when you got your car. Normally they try to negotiate it as well as other optional warranties. I normally just talk to the installer directly though and try to get a better price.

I do highly recommend a Clear Bra for any and all vehicles that come in contact with harsh conditions often. I see a lot of sand, gravel, debris around my area and the clear bra definitely helps preserve the paint.
