Car Scratch Repair Dublin panel

What are the potential problems we might run into if we don't fix these scratches? The blamishes don't really bother us, as long as the car runs well and is safe. We're not concerned about resale or trade-in value (it's a Hyundai, so it won't have any regardless), and we plan on keeping this car for at least 5-6 years, hopefully longer. I can think of several thousand things I'd rather spend $2,500 on other than this. But we should spend that money on repairing but less since Car Scratch Repair Dublin Panel costs less than that.
