Compound and polish both remove a very thin layer of clear coat to level defects. A compound such as AutoBead Heavy Cut Compound cuts fast to remove deeper scratches and sanding marks, while an ultra-fine polish such as AutoBead Finishing Compound refines light swirls to full gloss. Most corrections use a compound first, then a polish.
What is the difference between compound and polish?
How hard they cut and what they leave behind. A compound has coarser abrasives that remove deeper defects such as heavy swirls, sanding marks and deep scratches, but it can leave light haze. A polish has finer abrasives that remove light swirls and refine the finish to full gloss.
Compounding is the heavy correction step, and polishing is the refining step that follows it. Choosing the wrong one either wastes an afternoon or takes off more clear coat than the job needed, so the difference between polish and compound matters before you start.
What does a cutting compound do?
It levels deeper defects by removing paint faster. A cutting compound uses larger or harder abrasives, which is what lets it deal with heavier swirls, sanding marks, oxidation and random deep scratching.
The trade-off is that it can leave its own finer marring, often called hazing or micro-marring, which then has to be refined with a polish. That is why a cutting compound vs polish choice is rarely either or: on badly marked paint you use both, in that order.
What is a polishing compound?
A polishing compound, or simply a polish, is the finer of the two. It uses finer abrasives to remove the shallower defects a compound leaves behind and to bring up gloss and clarity.
Makers use the names loosely, so read what a product removes rather than what it is called: AutoBead calls its finest product a Finishing Compound, and describes it as an ultra-fine polish. On paint in good condition, a finishing polish alone may be all the car needs.
Which one does your car need?
Match it to the defect on your car: a polish for light swirls, a compound for deeper marks, then a polish to refine. Check the paint in good light first.
- Light swirls and holograms on otherwise good paint: a finishing polish on a soft pad.
- General swirl marks from years of washing: a medium cut compound, which can be enough on its own, or followed by a finishing polish.
- Deep scratches, buffer trails or sanding marks: a heavy cut compound on a cutting pad, then a polish to refine.
- A scratch you can catch with a fingernail: it is likely through the clear coat, and no compound or polish will remove it safely. Ask a body shop or the TDHQ team first.
Should you use compound or polish first?
Test with the polish first, and only step up to a compound if the polish does not clear the defect. Clear coat is finite: every correction stage permanently removes some, and it does not grow back.
So always use the least aggressive combination that fixes the defect. If the polish leaves marks behind on your test section, compound that area, then refine it with the polish afterwards.
Which pad should you use with compound and polish?
A firmer cutting pad for compound and a softer pad for polish. The pad is half the system: a finishing polish on a heavy cut pad behaves very differently from the same polish on a soft finishing pad.
- Heavy cut pad with a compound: deeper defect removal, expect to refine after.
- Medium pad with a medium compound or polish: the common all-round combination.
- Soft finishing pad with a finishing polish: maximum gloss, minimal removal.
- Microfibre pads: more cut than foam of the same nominal grade.
Which AutoBead compound and pad should you use?
Heavy Cut for deep defects, Medium Cut for general swirls or a one-step correction, and Finishing Compound for the final gloss, each with its matching Downforce pad. Every product below is in stock with us, and every claim comes from AutoBead's own listings.
For heavy defects such as random deep scratches, buffer trails and sanding marks up to 1500 grade. Its diminishing abrasives break down to a finish that needs little refining, and AutoBead recommends its Medium Cut Compound or a finishing polish afterwards.
Removes swirl marks, imperfections and sanding marks up to 2500 grade and leaves a high gloss, which is why AutoBead says it also works as a one-step correction polish.
An ultra-fine polish that AutoBead says removes light swirls, holograms and 3000 grit sanding marks without leaving marks or trails, even on softer paint.
AutoBead Downforce Foam Pads Heavy Cut
A dual foam design that AutoBead says stays firmer for longer under heat, with a dense backing for more downward pressure. It pairs with the Heavy Cut Compound.
AutoBead Downforce Foam Pads Medium Cut
The medium cut pad in the same dual foam design, paired with the Medium Cut Compound.
AutoBead Downforce Foam Pads Fine Cut
The fine cut pad, paired with the Finishing Compound, with a rubber-like backing that AutoBead says stops polish reaching the hook and loop.
AutoBead makes all three compounds silicone free with no fillers, so what you see after wiping off is the true finish. They work on DA or rotary machines.
| Product | Job | Removes | Pair with |
|---|---|---|---|
| AutoBead Heavy Cut Compound | Heavy correction | Deep scratches, buffer trails, sanding marks up to 1500 grade | Downforce Heavy Cut pad |
| AutoBead Medium Cut Compound | Correction or one step | Swirl marks, sanding marks up to 2500 grade | Downforce Medium Cut pad |
| AutoBead Finishing Compound | Finishing polish | Light swirls, holograms, 3000 grit sanding marks | Downforce Fine Cut pad |
What is a one-step polish?
A product made to cut and finish acceptably in a single pass. A one-step polish is a sensible choice when time matters more than the last few percent of clarity.
An all-in-one goes further and adds a filling or protective element, which is useful for a quick improvement but means you are no longer purely correcting. For finishing polishes from other brands, our best car polish guide compares them.
How do you do a test section?
Work a small area with slow, overlapping passes, wipe it off and check it in good light before you do the rest of the car. AutoBead advises an area no bigger than six times the size of the pad.
Paint hardness varies a great deal between manufacturers, and even between panels on the same car, so a test section on one panel tells you what the combination actually does on this paint.
What should you do before compounding?
Wash and decontaminate the paint first, because compounding over bonded contamination drags it across the panel.
After each stage, panel wipe to remove polishing oils before you inspect the result, or any oils left on the paint can flatter the finish and hide defects that reappear later.
Common questions
Can I use a polish without a compound?
Yes. If the paint only has light swirls, a finishing polish on a soft pad may be all it needs. Use a compound only when the polish does not remove the defects on your test section.
Do I need a machine?
A machine gives far more consistent cut and finish than working by hand, and a dual action polisher is the low-risk way in. Our guide to the best DA polisher explains orbit size, backing plates and pads.
Do I need to protect the paint afterwards?
Yes. Correction leaves bare, freshly refined clear coat. Protect it with a wax, sealant or coating, and our guide to wax vs sealant vs ceramic coating explains which suits you.
Not sure where to start?
If you are choosing your first machine, pads and liquids together, the combination matters more than any single item. Ask the TDHQ team what pairs sensibly rather than buying the most aggressive option, or browse the full AutoBead range.
