it will be noticable to YOU and others that are smart enough to pick it out. But if your worried about people on the road noticing, they wont.

Make sure when you get your car back from the shop to check the space between panels and doors. Ussually there will be a slightly bigger (or smaller) gap as compared to the other side(non-accident side). its hard to notice with the naked eye, but if you measure it and then measure the other side, youll see that its not the same size.
