I have been using Automotive Touch-Up Paint to fix chips and scratches in several of my cars. It is a company, based out of New Orleans that sells premium paint to body shops. They can mix any color (60,000 available) and the results are a perfect match. Highly recommended. I like their paint pen. It has a foam wedge and is great for small nicks. It only costs $13.95 for 1/2 ounces. Bottles sell for $10.95 (1/2 ounce) and $15.95 (2 ounces). https://www.automotivetouchup.com/
I've used them for many years. Solid recommendation. The only trouble they have, like every other paint company, is matching paint with cars that have been out in the sun or just old. Fading, especially reds, makes it impossible for any company to properly match. Everyone should keep that in mind.
I'm another member that can recommend this company. I've used the bottles and spray for a bunch of different cars with good results. Dupli-Color only produces certain paint codes across manufacturers, Automotive Touchup will match almost any color that has a paint code. I'm crossing my fingers that I'll never have to order B5 blue.
I haven't needed any on my current ride, but I've had very good results with Dr Color Chip . They have videos U . https://drcolorchip.com/
I just ordered the touch-up pen on for my Challenger with the clear coat. I have the Sinamon Stick color- hope it works.
This is one of the reasons I will stick with white colored vehicles. The color is much more forgiving in hiding swirls, blemishes, scratches in comparison to black or a red color car.
