Live with it. Dr. J. nailed it. Every time you roll into the dealer for any issue, you risk idiocy. I fix whatever I can myself, only go into the dealer if there's no other choice. The reason they want to spray your quarter is for blending, because they know damn well they can't match that metallic cold-turkey without spraying/blending into the 1/4 to obscure it. Painting 101.

Look at it this way, you'll always be able to identify your car is someone steals it..
