Chemical Guys, C4 Clear Cut Correction Compound for Paint Defects, 16 oz | Pro compound cuts swirls, holograms and scratches from clear coat, leaving a smooth, glossy, correction-ready finish

It works good with a little bit of effort. They used the buffer. It did not eliminate the scratches, but for an older car not so bad.

The Compound works great for restoring car paint. It removes scratches, swirl marks, and oxidation quickly while leaving a smooth, glossy finish. The compound is easy to apply and works well with both dual-action and rotary polishers. After using it, my car’s paint looked noticeably clearer and shinier. Excellent quality product from **Chemical Guys for anyone serious about paint correction

This compound works great. I would buy the set. The compound and the polish. I am on my 4th set, and I used to use 3M. Which is good. Polish and compound. But this works just as good in half the price.

I bought a used tank cover online and it was a complete mess. Hazing and tons of micro scratches. This stuff fixed it right up with a medium cut and then followed by a polish. It nearly looks better than new! My biggest complaint is that the bottle leaks pretty bad when the tab is up. The compound just finds a way around the tab and leaks out causing waste. Still happy with the results!

C4 Chemical Guys Compound is a solid product that improved the paint appearance of my car. At first, it was NOT noticeable because I had been using CG Extreme BodyWash & Wax for the past year. The car wash solution and regular car washing will keep my car shiny without the need for compound and polish. However, taking a deeper look at the paint with C4 application shows that the solution eliminated about 80% of the light scratches. These scratches, caused by car wash brushes and snow removal tools, were practically gone. While deeper scratches, like those from snow shovels or door contacts, were somewhat muted, they were not completely removed. Previously, I had no routine for addressing scratches on my car, which had accumulated over six years + plus three years before ownership. Thanks to C4's scratch removal, the depth of the Crystal Black Pearl paint became more visible. Throughout the day, I noticed the color really 'pops.’ To fully appreciate the progress, you need to examine the area closely in the dark with a flashlight. C4 is excellent for restoring paint to a high shine, but it won't completely bring back the car's original factory gloss. Regular hand washing will help reduce the frequency of compounding (I learned should only be done once or twice) and polishing (6 months or annually). I anticipate this DIY project will last until the fall. Realistically, since the car is not garaged, I don't expect the results to last more than six months, but time will tell. My advice compound and polish is better in the fall because I constantly have to rinse or take a microfiber cloth to see glossy with the daily dump of pollen and dust in May.

The hood and roof paint on my 2016 GMC sierra was getting unsightly oxidation and scratching from years of drive thru car washes and sun exposure. It was driving me crazy to look at. C4 is Easy to use. I applied, by hand, using the chemical guy orange hex application pad. I took my time so I didn’t ruin the clear coat. It took several applications. It took me a few hours to do the full hood, since I did it by hand and you can only do small sections at a time. A little product goes a long way… I have finished the hood and I am still working on the roof (no in progress photos of roof, only before) and I have only used 1/4 of the bottle of C4. I wish I took the time to take better before photos, but once I got started I was so pleased with the results I just kept going. I have not done the roof yet but included a photo of the roof to show what the hood looked like before using C4. You can see the difference in the photo showing the hood and the roof together. I have not used any polish/coating/wax yet on the hood, only C4 so far, and the shine is amazing… it is like a mirror (as you can see by the reflection of the cloudy sky in the hood). I highly recommend this product.
