SONAX PROFILINE NP "03-06" High-Gloss Polish (Finish) 250ml

Flawless high gloss as the final polishing step — SONAX PROFILINE NP 03-06

What does the SONAX PROFILINE NP 03-06 do? This fine high-gloss finishing polish pulls out the last holograms and buffer trails, brings up a mirror-like clear-coat shine and gets the paint ready for sealants and ceramic coatings — perfect as the final polishing step after abrasive correction stages.

In a multi-stage polishing job, the finishing polish is the real test of skill: it comes after the cutting polish and the medium correction polish, and its job is to clear out the last fine holograms, buffer trails and micro-scratches completely — leaving the clear coat with the kind of depth, clarity and reflection that sells a fresh detail. The SONAX PROFILINE NP 03-06 is the pro high-gloss finishing polish for exactly this last step: very fine cut, low haze, and a gloss that sets the paint up perfectly for sealing.

• Ultra-fine cut for hologram-free high gloss. The NP 03-06 carries very finely milled abrasives that level the buffer trails left by cutting and medium polishes without laying down fresh scratches of their own. What you get is a paint surface with maximum reflection and minimal orange peel — the base for that mirror-deep gloss a freshly detailed car is meant to throw back at you.
• Balanced viscosity for machine and hand work. The NP 03-06 is mixed so it runs on rotary and dual-action machines just as well as by hand on small panels. The viscosity lets it spread evenly across the pad, keeps it from slinging during machine work and stops it drying out too fast — which really matters on bigger panels, where you need to keep the working time consistent.
• Ideal as a pre-coating step before sealing. A finishing polish before you seal isn't optional if maximum sealant durability and top gloss are the goal. The NP 03-06 leaves no protective film and no waxy fillers — once it's done, the clear coat is ready for the degrease step and the sealant, with no abrasive residue getting in the way of coating adhesion.

Detailing1's tip from the shop: The NP 03-06 gives its best with a finishing foam pad on a dual-action machine — speed 3–4 (depending on the model), slow, overlapping passes. For the last pass, drop the speed to 2–3 to keep heat down and even the result out. Dose the polish sparingly: a small amount on the pad, spread it by working it in slowly by hand, then switch the machine on. After polishing, buff the area off with a clean microfibre and check for holograms straight away — under raking light (side light) you'll spot any leftover buffer trails most clearly. Once that check passes, the SONAX PROFILINE Prepare follows as the degrease step before sealing.

Abrasive technology: how the NP 03-06 high-gloss finishing polish clears holograms

A finishing polish works by mechanical micro-abrasion: the finely milled abrasives in the high-gloss polish cut the clear-coat surface at micrometre level, smoothing out the grooves and scratch marks left by earlier polishing stages and creating a surface that's as flat and uniform as possible. Light hitting a flat surface bounces back evenly — that's the physics behind the so-called depth gloss and the mirror reflection you see after a successful finishing polish.

The cut of the NP 03-06 is pitched just right for the final polishing stage: fine enough not to lay down new holograms, but still strong enough to clear out the buffer trails from the preceding medium correction polish completely. That balancing act is typical of finishing polishes — too fine a cut won't fully remove buffer trails, too coarse a cut creates holograms of its own that need another finishing pass to fix. The NP 03-06 carries the "03-06" in its name, which marks where it sits in the SONAX polishing range.

Another upside of finishing-polish technology is what detailers call "darkening" — on dark paint (black, dark blue, dark grey) a noticeably deeper colour comes up after the finishing polish, because the surface is so flat and clear that more light gets into the paint and reflects back. The effect is less dramatic on light colours, but still clearly there: the paint looks fresher, livelier and more even than before. On cars with black or dark paint especially, the finishing polish is the most visible step in the whole detail.

Using the NP 03-06 right — pad, machine and technique for the best results

The finishing polish assumes the prep is fully done: dirt, fallout and tar removed (decon step), the paint prepped with a correction polish, and the surface clean and dry. A finishing polish on an unprepped, heavily scratched surface can't clear the fine scratches completely — the step only pays off when the stages before it were done right.

Pad choice: for machine work, finishing foam pads (soft, no cut of their own) carry the polish's fine abrasives evenly onto the surface without adding any cut. Hard foam pads or microfibre pads with their own cut aren't ideal for a pure finishing polish — the NP 03-06 is built for soft finishing pads. For hand work, use a soft, clean applicator — on small areas (headlights, small dent zones) the polish works well by hand too, but on large panels machine work is a must for an even result.

Technique: lay the polish down, spread it at the lowest speed, then run several overlapping passes across the panel at medium speed. The last pass goes at a slightly reduced speed and light pressure — this final pass levels the faint cross-marks the polishing leaves behind. Watch the dry-down: if the polish flashes off too fast (in the sun, on hot paint) it won't work properly — ideally polish in the garage or in the shade. After buffing off with microfibre, check for holograms straight away — any leftover buffer trails show up best under side-on artificial light.

Where the NP 03-06 fits — when a finishing polish is the right step

The NP 03-06 is the final polishing step before any sealant or ceramic coating. You reach for it when there are still fine buffer trails or holograms left after the correction polish that need clearing before you seal. Typically the NP 03-06 is step 3 or 4 in a multi-stage polishing job: after the cutting polish (hard pad + cutting compound) and the correction polish (medium pad + medium polish) comes the finishing polish as the last abrasive step.

On cars that don't need heavy correction (nearly new paint, or paint with very fine swirl marks only visible at an angle), the NP 03-06 can also run as the only polishing stage — a so-called "one-step finish". Here you pair a lightly cutting pad (combo pad) with the finishing polish to knock back light swirl marks and bring up maximum gloss in one go. That approach saves time, but it isn't enough for deeper scratches and heavier holograms — there a multi-stage process with a proper correction polish is unavoidable.

On delicate cars with a thin clear coat (often older cars after several previous-owner polishes, or certain makes like Porsche and some BMW models) the finishing polish is especially valuable, because it gets by with minimal paint removal — the light cut clears only the buffer trails, without taking off more clear coat than needed. Paint-depth readings before the job help judge how many polishing passes still make sense without thinning the clear coat too far.

NP 03-06 vs. PerfectFinish — which finishing polish for which job?

The SONAX PROFILINE range has two finishing polishes for different demands. The SONAX PROFILINE PerfectFinish "4/6" sits as the more aggressive finishing polish with a slightly higher cut — it's built especially for use after P2000 sandpaper (hence the "up to P2000" tag) and suits situations where a bit more cut is needed after sanding to clear the sanding marks completely. The NP 03-06, by contrast, is the finer finishing polish for the last step after the polishing correction stage.

In practice: if you're polishing after wet sanding (e.g. after removing a deep dent or a respray), you pick the PerfectFinish as the first polishing step and optionally the NP 03-06 as the final hologram removal. If you've worked a normal detail without sanding using a correction polish, you only need the NP 03-06 for the finish step. For detailers who want both scenarios covered day-to-day, having both polishes on hand makes sense — the PerfectFinish for sanding-heavy work, the NP 03-06 for pure high-gloss finish steps after polishing.

On pad compatibility and machine suitability the two finishing polishes are similar — the call comes down mainly to the cut you want and the prep stage before it. For maximum flexibility in a pro setup we recommend keeping both polishes available, since the exact state of a car often only becomes clear on the lift and under correction lighting.

Buy SONAX PROFILINE NP 03-06 — bottle sizes and value

The SONAX PROFILINE NP 03-06 comes in three sizes: 250 ml for beginners and occasional use, 1 litre for regular detailers and pro detailing businesses, and 5 litres for high-throughput operations or for training sessions. The price per millilitre drops noticeably with the bigger bottle — for businesses polishing several cars a week, the 1-litre or 5-litre size is the most economical choice.

Per application on an average car (saloon or compact) you'll use about 15–30 ml of polish, depending on the number of passes and the pad size. The 1-litre bottle covers around 30–60 full car polishes that way — excellent value for regular use. The 250-ml bottle suits beginners who want to get to know the polish first, or special jobs on small areas (bonnet, roof, single panels after a spot repair).

As a complete finish workflow we recommend: NP 03-06 (high-gloss finishing polish) → SONAX PROFILINE Prepare (degrease/panel wipe) → SONAX PROFILINE PolymerNetShield or a ceramic coating. This three-step finishing workflow makes sure the paint glosses to the max after the detail, is fully degreased and stays protected long-term under a quality sealant — the standard for professional detailing results.
