Chemical Guys C4 & P4 Clear Cut Correction Compound and Precision Paint Perfection Polish Combo - Removes Scratches, Swirls, Towel Marks, and Etching, Restores Gloss, Polishing Kit - 2 x 16 oz

I added this to my growing Chemical Guys lineup and have been happy with the results, especially for the cost. It’s not the most aggressive product out there, but that’s not what it’s meant for. This works really well as a mid-step polish. I was able to remove light scratches and swirl marks without damaging the paint, and it brought back a nice, clean shine. It’s a good follow-up after using a more aggressive compound—helps refine the finish and clean up any haze left behind. Like most detailing products, this isn’t a one-size-fits-all solution, but Chemical Guys does a good job offering different options for each step of the process. Pros: Great for light scratches and swirl removal Leaves a nice shine Good value for the price Cons: Not strong enough for deeper scratches Best used as part of a multi-step process Bottom line: A good mid-level polish that delivers solid results for the money. Great addition to a detailing kit if you’re doing more than just basic wash and wax.

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

I bought this product to see how good it was, tested it and OMG (IT WAS FENOMINAL) easy to use easy to take off and left a shine I could not believe, got rid of All the swirls and blemishes on my black motorcycle!!! I RECOMMEND THIS TO A 5 year old that’s how EASY it is!! Video to follow!

I was pleased with the result. I cleaned up a 10 year old paint job. Removed light surface scratches. Easy to use but a time consuming process. Took about 5 hours to do both coats.

I recently ordered the Chemical Guys C4 & P4 Clear Cut Correction Compound and Precision Paint Perfection Polish Combo packet. I am planning to sell my Benz and decided to try and make the car look detailed. I did my research and compared reviews, costs, and instructions and found that this product had great reviews and the cost was in-line with that of other similar products. The products arrived on the day indicated and the directions were easy to follow. Application of the products were easier than I anticipated and can be applied with a buffer or by hand. Since the Cut Correction is removing built up dirt and corrosion, it is important to wash the vehicle before using. I already had a handheld buffer so I decided to buff the car with the Cut Correction. All of the corrosion and slight scratches were easily removed. I tried buff out some of the deep scratches, but was less successful even with multiple attempts. However, these scratches are through the paint and I was just taking a long shot at success. However, overall the Cut Correction did a good job. While the Cut Correction does not indicate using the products on the headlights, my headlights were heavily scratched and had started turned yellow. I was recently had a detailer quoted $90 per headlight for cleaning them. I was delighted that the Cut Correction worked great removing all the corrosion and scratches, even the embedded dirt. Please note that if your vehicle is a light color you will need to take care to wipe away all of powered build up from the Correction Cutting. After buffing, I next tried the Precision Polish. The polish can also be applied with a buffer or by hand. The instruction stated that I would end up with a “mirror like finish”. However after trying the polish on the trunk, the finish was much duller than I expected and did not have a wet look. I must admit that I have been spoiled by using a ceramic polish (see my previous review of Fortify Shine Armor) and always receive a wet gloss look. I am giving this product a 4 star review based the exceptional job with the Cut Correction. However, there are more effective polishes on the market.

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.

I was told that nothing would refresh the paint on my 2007 Toyota. After much reading I settled on Chemical Guys products and videos. The photos of my car speak for themselves! Car looks amazing. The polish work great and are easy to use. It’s a perfect size and it’s a great value! Recommend!

I was skeptical but it works really good. The “before” pic was in the shade, so the lighting is off it’s 82 degrees here, the “after” pic was after a car wash.

I love it, easy to use. My Black faded car look nice and Shiny now ❤️ Delivery was on time.

Its a quality product even for amature enthusiast.
