CARPRO UltraCut Extreme Cut Compound 250ml (8oz)

The 250ml (8oz) bottle of CARPRO UltraCut compound is the smart way to put the most aggressive cutter in the CARPRO range through its paces without committing to a full liter. Same extreme cut formula — advanced abrasives engineered for deep scratches, heavy oxidation, and paint everyone else has given up on — in a size that fits a weekend correction project.

The UltraCut Compound, Sized for a Test Drive

Plenty of detailers only reach for UltraCut when a job truly calls for it: a neglected trade-in, a hood full of sanding marks, a clear coat gone chalky. For that kind of occasional-but-serious work, 8 ounces keeps a genuinely professional-grade compound in your cabinet without tying up money in product you will use twice a year.

Using UltraCut on your first correction:

• Always begin with a test spot — UltraCut removes defects fast, so confirm your pad-and-pressure combination on a small area before committing to the panel.
• Start on a foam pad and step up to microfiber or wool only if the defects survive.
• Keep the pad moving and let the abrasives do the work rather than leaning on the machine.
• Remove residue, inspect the paint, and repeat only where needed.
• Plan a finishing-polish pass afterward — extreme cut leaves haze by design.

Which size is right for you? This 8oz bottle is the trial-and-project size. Once UltraCut earns a permanent spot in your rotation, the 1 liter (34oz) bottle is the better buy — the per-ounce cost drops substantially at that volume.

Can I run UltraCut on a dual action polisher like the Maxshine M8S?

Yes — UltraCut runs happily on a DA. Pair it with a microfiber or foam pad and let pad choice and machine speed set the cut; wool on a rotary is the setup for the most severe defects.

What's the difference between UltraCut and ClearCut?

UltraCut is CARPRO's maximum-cut option for severe damage, while ClearCut is a heavy cutter tuned for low dusting and a cleaner wipe-off. If the paint is merely rough, ClearCut may be all you need; if it is wrecked, this is the bottle.

Do I need a finishing polish after UltraCut?

Almost always. Follow with Reflect to clear the compounding haze before any coating or sealant goes on.
