well rust proof and that paint sealer seems like something that can happen. I agree the buyer has to pay attention to things. A lot of thing dealers will automatically do and they do it on all cars, I have caught them on this before. And I have seen people so wrapped up in the driving experience that the dealer asks them questions and they head nod everything. I would say that if you do not take a look at your order sheet and confirm everything you are partly to blame.
