Fender Blending question

Pintsize725

"We mark up prior damage as well as what is to be repaired. It was a rock chip that was cleared over, you shouldn't have any issues with it spreading unless you mess with it. If we called every customer about prior rock chips before performing work, we would be doing that all day. It's pretty hard to see, but I know you're meticulous with your car, it's very well kept. Unfortunately if it spreads, there is nothing we can do to fix it under our warranty but we can do a customer write up. You're looking at $500-$600 for the fender and door repaint."
