Chemical Guys, C4 & P4 Compound & Polish Paint Correction Kit, 2 x 16 oz | Cut scratches, swirls and towel marks with C4, then refine depth and gloss with P4, safe on clear coat paint

I’ve used several polishing compounds over the years, and I was honestly impressed with the performance of Chemical Guys C4 Clear Cut Correction Compound and P4 Precision Paint Polish. The cutting ability of C4 is above average—it worked well at removing noticeable imperfections, oxidation, and swirl marks while still leaving a finish that was easy to refine. The P4 polish did a great job following up by bringing back the gloss and leaving the paint looking smoother and more reflective. What stood out to me was how well the two products worked together without feeling overly aggressive or difficult to control. The consistency made them easy to work with, and they spread evenly without making a huge mess. Whether you’re correcting a neglected finish or just trying to bring back that deep shine, this combo delivers results that are impressive for a DIY detailer. Chemical Guys definitely put together a quality correction system here. I would recommend it to anyone looking to take their paint correction results to the next level.

I was extremely skeptical this would help with scratches on my truck after I went through some bushes and trees off-road. I figured for 35 buh it was worth a try. I am beyond words how it got 95% of the scratches out and the one that still remains is hardly noticeable. I'm sure if I worked on it some more that would come out, too. And it even improved some scratches that are 8 years old. Still have half a bottle left of each. It's just amazing.

I have a black truck that is 7 years old. While the paint was pretty good, it had swirl marks as well as several scratches. I already had the CG DA buffer, so I decided to try the C4/P4. I followed the directions closely and the results were impressive. I was in a hurry when I started, so the results would have been even better had I taken my time. Make sure to follow up with a good wax after you are done.

Very good compound and polish combo. Took most of the paint surface blemishes out. The C4 did not cut as well as I wanted, but, that might have been me not wanting to press too hard first time using new products and buffer. That and was working on my 99 vette... harder clearcoat than modern finished. Easy to work with and did bring up luster even just a little. As I said good combo.

I 100% recommend. You have to put in some elbow grease but the results speak for themselves. It removes scratches after the first good pass. It smells amazing and it's easy to remove with a new microfiber towel. I recommend applying it with "Chemical Guys BUFX_204 Hex-Logic Hand applicator. C4 with orange pad and the white one for P4.

Worth every penny, if you know how to cut

Wow! What a difference this stuff makes. Easy to use and made my bike look new again.

Gives a great shine and smells pet good honestly!

Its a quality product even for amature enthusiast.

El mejor equipo de pulimentos para entusiastas del detailing, tienen fillers que facilitan en el proceso. Tienen aroma graduable

Bon produits et très bon services.

Excelentes productos, muy fáciles de aplicar con máquina

El C4 hace su trabajo, cumple con el marketing hecho por CG, deja la superficie lisa y lista para pulir. El único pero que le pongo es que no me elimino todos los swirls de la pintura aún haciendo dos pases con pads de corte. El P4 buen trabajo, limpia lo del C4 y deja la pintura preparada para encerar, pero creo que me sigo quedando con el mismo producto de CG All polish (la que pule, sella y protege y es de color semi amarillo)
