SONAX PROFILINE SP "06-02" Sanding Polish (Heavy-Cut) 250ml

Removing Deep Scratches, Sanding Marks, and Overspray with SONAX PROFILINE SP "06-02"

What can SONAX PROFILINE SP "06-02" do? The silicone-free heavy-cut abrasive polish with an abrasive grade of 6 removes sanding marks up to P1200, overspray, etching, and deeply embedded scratches on all paints — as the first step in a professional polishing workflow.

In professional paint detailing, there's no "one-size-fits-all" polish. A high-quality multi-step workflow divides the work: first, a heavy-cut polish removes severe defects, then a finish polish refines the result until the paint is free of sanding marks and achieves maximum gloss. This is exactly the role of the SONAX PROFILINE SP 06-02 as the first and most powerful step — a silicone-free abrasive polish with an abrasive grade of 6, developed for use with a rotary polishing machine. It removes sanding marks from wet sanding processes up to P1200, overspray, etching caused by bird droppings, insects, and tree sap, as well as heavily weathered single-stage paints. The SONAX PROFILINE SP polishing system is firmly established in the professional paint detailing sector: the clearly defined abrasive and gloss levels allow for precise planning of a multi-step workflow, where each polish performs exactly what it was developed for — and the SP "06-02" is the strongest and most abrasive tool in the entire set. It represents the first, crucial step, without which subsequent refining steps would not be able to unfold their effect.

• Abrasive grade 6 for defects that other polishes cannot tackle. Deeply embedded scratches, sanding marks after wet sanding with P1000 or P1200, baked-on overspray, and heavily oxidized paint surfaces: these are the application areas for which the SP "06-02" was designed. Conventional medium-cut polishes with abrasive grades 4 or 5 fail at these tasks — the SP "06-02" systematically and controllably eliminates them, without removing unnecessary paint material.
• Silicone-free — suitable for rework and painting. Silicone-containing polishes leave residues that are difficult to remove and can lead to fish eyes and adhesion problems during subsequent painting or sealing work. The SP "06-02" is completely silicone-free — it leaves no traces that hinder later correction work on the paint, making it the standard for professional paint detailing and workshops that also do repainting.
• Defined abrasive pattern for predictable subsequent polishes. The SP "06-02" creates a defined, uniform abrasive pattern on the paint, which can be precisely and efficiently refined with the subsequent polish PROFILINE FS 05-04. The coordinated abrasive and gloss levels in the PROFILINE system are no accident — they allow for a workflow where the next step always builds on the previous one, without unnecessary intermediate steps or rework.

Practical tip from Detailing1: Always apply the SP "06-02" to a clean, dust-free paint surface and degrease the surface beforehand with an IPA mixture (isopropyl alcohol) to remove residues from waxes or care products. In the first pass, use higher pressure (5–10 kg) at a lower speed (800 rpm) to activate the abrasive and remove the defect. Then reduce pressure and increase speed (1200 rpm) for the polishing-out phase. Always work in a checkerboard pattern to avoid transitions. After the SP "06-02", always check the defined abrasive pattern under good lighting before proceeding with the FS 05-04.

Abrasive grade 6 and gloss level 2 — how SP "06-02" deals with paint defects

The SONAX PROFILINE system defines abrasive and gloss levels on a scale that makes it easier to select the right polish for each degree of defect. Abrasive grade 6 is the highest abrasive grade in the SP range — it corresponds to an aggressive cut that also tackles stubborn defects such as deeply embedded scratches and wet sanding marks up to P1200. At the same time, gloss level 2 means that the SP "06-02" leaves a certain haze after polishing, which needs to be further refined by a finish polish. This is not a disadvantage, but the plan: a heavy-cut polish that simultaneously produces maximum gloss always compromises either the cutting performance or the finish. The SP "06-02" is optimized for the first step — and performs this step so well that the second step with the FS 05-04 becomes efficient and predictable.

The abrasive formulation of the SONAX PROFILINE SP 06-02 works with mineral abrasive particles that become actively abrasive under the polishing pressure of the rotary polisher. These "breaking down" abrasives break down during the polishing process: in the first pass with high pressure, they act with their full aggressiveness; in the second pass with reduced pressure, they become finer and create a more uniform abrasive pattern. This self-dissolving behavior is the reason why the SP "06-02", despite its abrasive grade of 6, delivers a controlled and predictable result — the paint is not removed uncontrollably, but systematically processed. If you want to understand why professional detailers appreciate the PROFILINE system, you will find one of the central reasons here: the chemistry works with the machine, not against it.

Important for practical use: the SP "06-02" is designed for use with a rotary polishing machine, not eccentric machines. Rotary machines generate the necessary heat and pressure to optimally activate the abrasives. With an eccentric machine at a low abrasive grade and moderate pressure, a heavy-cut polish can theoretically be used, but the result and efficiency are significantly worse. In professional use, for which the SP "06-02" is designed, only the rotary machine is used — ideally with a lambswool pad for maximum cutting performance or a hard foam pad for a controlled abrasive pattern on more sensitive paints.

Applying SP "06-02" correctly — the workflow with a rotary polishing machine

Phase 1 begins with a prepared paint area, free of dust and dirt. The panel to be worked on should also be at room temperature — cold paint reacts differently to abrasives than warm, and at temperatures below 10 degrees Celsius, the polish cannot develop its optimal effect. Apply product to the pad — not too much, about 4–6 pea-sized drops for an area of about one square meter. Then start with 5–10 kg pressure at 800 rpm and guide evenly over the area to be worked on. The higher pressure activates the abrasives and ensures that defects are removed efficiently. This phase lasts about 30 seconds per square meter and is the actual sanding process.

Phase 2 follows immediately: reduce pressure to 1–2 kg, increase speed to 1200 rpm. Now the SP "06-02" switches to the polishing-out phase. The finer abrasive particles level the surface created in Phase 1 and create the uniform, defined abrasive pattern that serves as the ideal starting point for the subsequent FS polish. This phase lasts about 60 seconds per square meter. Afterward, remove residues with a clean microfiber cloth and check the result under good lighting — ideally with an LED diagnostic lamp. If defects are still visible, repeat the phase before applying the next polish. The checkerboard pattern is important here: even overlaps of 50% of the pad surface prevent transitions and uneven material removal depths.

A practical tip for pad selection: The SONAX PROFILINE lambswool pad provides the highest cutting performance with the SP "06-02" and is the first choice for hard-to-reach defects or large-area weathering damage. The hard foam pad offers slightly less aggressiveness, but a more uniform abrasive pattern and less heat generation — ideal for more sensitive paints or if you want to control the removal more precisely. The decision between the pads therefore depends on the paint condition and the task: the more aggressive the defects, the more likely lambswool; the more sensitive the paint, the more likely a hard foam pad. If you have both pads in the set, you can switch from lambswool to the foam pad after the first round to further harmonize the abrasive pattern before the FS 05-04 — this often saves a separate polishing pass.

After the SP "06-02", the paint is in a state that still shows holograms and fine sanding marks under direct light — this is intended and expected. The purpose of the subsequent polish is precisely this: to further refine this defined abrasive pattern until the paint is hologram-free and highly glossy. Using the SP "06-02" as a sole polish and applying wax over it would not be effective — it is the first, not the last step.

Application areas — when the SP "06-02" is the right choice

The SP "06-02" comes into play in situations where medium-cut polishes are no longer sufficient: freshly repainted panels with orange peel or grit marks, vehicles with deep swirl marks after years without professional detailing, heavily weathered single-stage paints on classic vehicles, and especially post-treatment after wet sanding with P1000–P1200. In damage repair — after hail damage with small sanding spots, after bird dropping etching that has penetrated deep into the clear coat — the SP "06-02" is the tool of choice because medium polishes do not fully reach the depth of these damages. Also in overspray removal, where the abrasive effect is necessary to abrade the superimposed foreign paint particles, the SP "06-02" shows its full strength.

The SP "06-02" has limitations on extremely thin or already heavily thinned paints. For vehicles that have already undergone multiple professional detailing treatments and whose clear coat has little residual thickness, the paint thickness should be measured before using a heavy-cut product. This is not a disadvantage of the SP "06-02" — it is a general principle of any abrasive treatment that is automatically taken into account in professional use. The SP "06-02" removes defined and controllable amounts of paint when applied correctly and is not a tool for the casual user without experience with rotary machines. Professional detailers generally recommend always working on a test area in a less visible spot before the first use on an unfamiliar vehicle to get a feel for the paint hardness and removal rate — every paint reacts slightly differently, and what works effortlessly on a soft Japanese clear coat requires significantly more machine pressure and dwell time on a hard German clear coat.

SP "06-02" in the polishing system — the three-step workflow with PROFILINE

The SONAX PROFILINE polishing system is designed as a coordinated three-step system. First step: The SP "06-02" as a heavy-cut polish removes coarse defects and creates the defined abrasive pattern. Second step: The PROFILINE FS 05-04 — a medium-cut finish polish with an abrasive grade of 5 and gloss level 4 — refines the result of the SP "06-02" and eliminates the holograms and sanding marks created in the first step. Third step: The PROFILINE NP 03-06 achieves the final high gloss with an abrasive grade of 3 and gloss level 6 and leaves the paint in a swirl-free condition, ready for all sealants and protective products. This gradation from 6 over 5 and 4 to 3 and 6 is no coincidence — it reflects a carefully developed progression that delivers exactly what the next step needs at each stage.

If you have fewer defects and want to get by with a single polish, you can use the PROFILINE UltimateCut — a high-speed abrasive polish designed for one-step use on eccentric and rotary machines. The UltimateCut is aggressive and efficient, but not as strong as the SP "06-02" and at the same time delivers a better finish — a compromise that makes sense for many everyday detailing tasks. If, on the other hand, you need maximum cutting performance with a clearly defined follow-up workflow — and this is the typical demand in professional paint detailing — the SP "06-02" in a complete three-step system is optimally positioned.
