You probably have rock chips if you daily drive your car. Everyone gets them! I recently got an opportunity to test out the Dr. ColorChip system on my friend's 2023 F150 which clocked over 50,000 miles in a year and a half! This is a very interesting product and I thought it was quite easy to use.
I think compared to a paint pen or the little brush style touch-up paint this is a much easier way for somebody who's a novice to be able to achieve a high quality result. I was very impressed with that aspect of the product. It really doesn't take very much to get familiar with using it and achieve good looking results.

That blending solution lets you undo mistakes; Let's say you screw up. You can always remove the paint with that bending solution and start over. Being able to try again is a big deal for people who are less confident in making such repairs. Typically the biggest complaint with traditional systems like paint pens is staying within the margins, you have to have a real steady hand to achieve a fully filled and flat look.
