Sanding and Polishing Paste for Targeted Paint Correction

Sanding and polishing paste removes scratches, sanding marks, and weathered layers of paint, thereby restoring the paint’s original shine. It is used wherever a standard polish is no longer sufficient—such as for deeper scratches, coarse sanding marks from the sanding process, or heavily weathered surfaces. Within paint care, sanding and polishing paste thus covers the more intensive correction stage, while classic polish is intended more for superficial refreshing.

Depending on the product, these range from small pastes for spot application by hand to sanding polishes for use with rotary or random-orbit polishers, which are used on larger surfaces or in professional detailing shops. Which product is suitable depends primarily on the extent of the paint damage and whether the work is done by hand or with a machine.

Properties and Benefits of Abrasive and Polishing Pastes

Sanding and polishing pastes are designed for targeted material removal, allowing scratches and sanding marks to be reliably removed. How aggressively a product works and how fine the result is varies significantly depending on its composition.

Typical characteristics:

• Targeted removal of scratches, sanding marks, and weathered paint layers
• Designed for manual application or for rotary and eccentric polishers, depending on the product
• Several products are formulated without silicone
• Varying abrasive performance, ranging from spot correction to broad-area sanding and removal
• Some products are suitable for all types and colors of paint
• Part of the correction stage in paint care, prior to the final polishing or sealing

Which properties apply in each specific case depends on the selected product and the actual condition of the paint.

Which sanding and polishing pastes are suitable for which applications?

SONAX SchleifPaste is suitable for spot treatment of individual scratches or etch marks by hand. According to the product instructions, it is applied with a polishing pad and also removes damage caused by bird droppings, insects, or tree sap—cases where regular polishing is no longer sufficient.

SONAX PROFILINE UltimateCut is suitable for machine-based correction of large areas requiring heavy sanding. According to the product instructions, it removes sanding marks from P1000 grit particularly quickly and is designed for very large surfaces such as RVs or boats.

SONAX PROFILINE PerfectFinish is ideal for the hologram-free finishing step following a sanding and polishing process. According to the product description, it removes sanding marks up to P2000 grit and can sometimes be used in a single step on light-colored surfaces.

What should you look for when buying sanding and polishing compounds?

First and foremost, the extent of the paint damage is crucial: For isolated, localized scratches, a small tube of hand polish is usually sufficient, while paint that is weathered or scratched over a large area requires a sanding compound and a polishing machine.

The method of application also plays a role: Those working by hand should use pastes with a polishing pad, while machine use requires a suitable rotary or random-orbit polisher with an appropriate pad.

In multi-step restoration processes, it’s also important to consider whether a product is intended for the first, coarse correction step or for the final, hologram-free finish within the paint care routine—both steps have different objectives and cannot be replaced by the same product.

Hand paste, abrasive polish, or finishing polish—which grit size is right?

Hand polishes such as SchleifPaste are designed for anyone who wants to repair isolated, clearly defined areas of damage without a polishing machine. They are intended for spot treatment and are not meant for large-area application.

Sanding polishes like UltimateCut, on the other hand, handle the coarse correction step: They remove significantly more material but require a polishing machine and are designed for speed when working on large areas.

Finishing polishes like PerfectFinish take a third approach, as they refine the surface to a finer finish and produce a hologram-free shine rather than relying solely on material removal.

None of the three variants is inherently preferable—the decisive factor is whether spot correction by hand, coarse machine removal, or a fine finishing step is required.

Application and Instructions for Sanding and Polishing Compounds

Before each application, the paint should be thoroughly washed, as loose particles can cause additional scratches during polishing. Hand polishes are applied with a polishing pad and used selectively on specific areas, not spread over the entire paint surface.

According to the product instructions, machine-applied sanding polishes should be applied evenly with a suitable pad and worked in several short passes rather than one long one to achieve an even result. Never work on hot surfaces.

After sanding or polishing, remove any residue with a soft microfiber cloth before sealing or waxing the paint in the next step. Be sure to follow the manufacturer’s instructions regarding pad selection and pressure.

Complementary Products for Paint Care

• Polishing Machine Accessories
• Car polish
• Paint cleaner

Polishing machine accessories provide the appropriate pads and application tools for the mechanical application of sanding and polishing compounds. Car polish is a gentler alternative for paint that does not require such heavy removal, while paint cleaner creates a clean starting surface for an even sanding and polishing process as part of paint care.
