SONAX PROFILINE Prepare Cleaner & Inspection Spray (Degreaser) 400ml

Degrease and inspect your paint before sealing — SONAX PROFILINE Prepare

What does the SONAX PROFILINE Prepare do? This cleaner and inspection spray degreases paint surfaces with zero residue before you lay down sealants and ceramic coatings — and at the same time it makes leftover polishing oils and silicone residue show up thanks to the inspection effect.

Every proper sealant, every ceramic coating and every protective-film job starts with one step you can't skip: getting the surface fully degreased. Oils, silicones, polishing residue and release agents are invisible contaminants that wreck the chemical bond of a sealant — a surface that isn't degreased gives you patchy bonding, shorter durability and visible flaws. The SONAX PROFILINE Prepare is the dedicated degreaser and inspection spray for this make-or-break step: fast-acting, residue-free, and at the same time usable as an inspection spray that makes any leftover contamination visible through how the light refracts off it.

• Residue-free degreasing before sealant and coating. Polishing oils, silicones and other release agents are hydrophobic substances that cling to the paint if you don't pull them off on purpose. The Prepare loosens these contaminants and lifts them off the paint as you wipe — without leaving residue of its own that could mess with the sealant going on next. A cleanly degreased surface is the one condition that lets polymer or ceramic sealants reach their full bond and durability.
• The inspection effect makes contamination visible. On top of cleaning, the Prepare spray has an important inspection job: spray it onto the surface and any spots with oil residue or polishing oil show a telltale running of the spray film. Spots with no contamination, on the other hand, wet out evenly. That visual cue lets you go back and clean those exact spots before the sealant goes on — a quality-control move no serious detailer leaves out.
• As a prep spray and panel wipe in your detailing workflow. The Prepare works both as a surface degreaser before coating and as a panel wipe after paint correction (polishing) — to fully strip polishing-oil residue before sealing. So it's not just a sealing-stage product; it slots into the full reconditioning workflow (polish → panel wipe → coating) as an integral step.

Detailing1's tip from the shop: Always use the Prepare right before you lay down the sealant or coating — not hours earlier, since dust and ambient contamination can settle straight back onto the cleaned surface. Spray it onto a clean, lint-free microfibre cloth (don't spray it straight onto the paint, to stop it running uncontrolled), wipe the panel you're about to seal, then flip to the dry side of the cloth right away to take it off. Work in a garage or an enclosed room with no draught to avoid fresh contamination. Straight after the Prepare, lay down the SONAX PROFILINE PolymerNetShield or a ceramic coating.

Degreaser and inspection spray — how the Prepare gets surfaces ready for coatings

The degreaser-inspection spray works off fast-evaporating solvents that loosen grease, oils and silicone residue on the paint and lift them off with the wipe cloth. Unlike water-based cleaners, these solvents leave no moisture film behind once they flash off — the evaporation is complete and residue-free, which is the ideal base for the coating going on right after.

The real value sits in the dual job: while the spray cleans, the visual inspection effect shows you where contamination is still hiding. That effect comes down to the different surface tension of contaminated versus clean paint: on degreased paint the spray spreads out evenly as a fine film, on contaminated paint it pulls together and shows telltale craters or beads. This matters most when the panel you're coating wasn't fully oil-free after polishing — even small amounts of polishing oil can permanently hurt a ceramic coating's bond in that spot.

In professional reconditioning, the panel-wipe step with a degreaser like the Prepare is a quality standard no serious detailer skips: ceramic coatings like the SONAX PROFILINE HybridCoating "CC One" bond chemically to the clearcoat — a grease layer that blocks that bonding zone cuts the bond quality and can lead to peeling or patchy protection months down the line. The few minutes a careful degreasing step takes pay off in clearly better durability and a more even coating.

Using the Prepare right — the panel-wipe workflow step by step

Using the panel-wipe spray is simple, but how cleanly you do it decides the final coating result. Prep: the car has to be fully washed and dried before the degreasing step — the Prepare is no cleaner for dirt or dust, only for oily and silicone residue on an already washed, dry surface. Water and dirt left on the surface block the degreasing effect and leave streaks.

Application: the microfibre cloth for the Prepare should be new or freshly washed — a cloth that has already soaked up polishing oil hands it straight back to the paint as you wipe and undoes the whole degreasing effect. Spray the Prepare onto the cloth (not onto the paint), so the amount of solvent stays controlled and nothing dwells uncontrolled on sensitive paint areas. Wipe across the panel with light to medium pressure — the inspection effect shows up right away: even wetting signals a clean surface, patchy spread flags up oil residue. Go back over it until the wetting is even.

Removal: right after wiping with the wet side of the cloth, take it off with the dry side or a second clean cloth before the solvent flashes off fully. That way the loosened grease and oils come off the paint instead of getting rubbed back onto the surface. Lay down your chosen sealant straight after — no pause, since the degreased paint is now at its most ready to take the coating chemistry. On big cars work in sections: Prepare, then sealant right after, section by section.

Where you use it — when degreasing before sealing is a must

The degreaser spray is a must in several spots in the detailing workflow. The most common case is the panel wipe after paint correction: every polish frees up polishing oil that works as a lubricant and abrasive carrier between pad and paint. After polishing, that oil film sits on the paint — an even, fine, but bond-killing layer for sealants. The Prepare strips this film fully and gets the freshly polished clearcoat ready for sealing right away.

The second common use is prep for protective films (PPF — Paint Protection Film): films bond with adhesive layers on the paint and need an absolutely oil- and silicone-free surface for the best bond and edge sealing. Even small silicone spots under the film can lead to air bubbles, incomplete bonding and later peeling — a flawless degreasing step with the Prepare is therefore a particular pro standard on PPF jobs. Degreasing also matters when re-sealing cars that were treated with wax or polymer products before: old wax and polymer residue on the paint can noticeably hurt a ceramic coating's bond in those spots.

The Prepare also earns its keep for quality control after polishing, whatever sealant comes next: the inspection effect shows whether the polish was carried out evenly across the whole panel, or whether areas with polishing residue point to spots that haven't been worked yet. So the Prepare doubles as a quality-control tool that flags gaps in the polishing work and heads off flaws in the final sealant before they get locked in.

The Prepare compared — degreasers and IPA mixes for paint prep

In professional detailing there are several products used as degreaser and panel wipe. Isopropyl alcohol (IPA) in diluted form (typically 10–20% in water) is a classic panel wipe that's cheap and widely available — the degreasing works well, but the inspection job is missing. If you degrease with IPA, you have to trust other cues to judge whether the degreasing step is complete. The Prepare gives you a clear edge here: the visual inspection effect gives you instant feedback on the quality of the degreasing step.

Next to all-purpose degreasers or solvent-heavy cleaners, the Prepare positions itself as a gentler, more paint-friendly product — not every solvent goes onto sensitive clearcoat, fresh multi-layer paintwork or coated surfaces without trouble. The Prepare is formulated specifically for car paint and safe on all common clearcoat grades. On fresh factory resprays or repair paint do a quick test patch to make sure it's compatible — especially on very freshly applied clearcoat that hasn't fully cured yet.

Compared with cross-brand degreasers, the PROFILINE Prepare has the edge of system compatibility: it's matched to the PROFILINE sealant line and leaves no residue that would clash with the PROFILINE coating products. For detailers running a fully matched product system, that's an important quality factor — systematic compatibility cuts risk and makes results more repeatable. The SONAX PROFILINE PerfectFinish "4/6" as the finish polish before, and the Prepare as the panel wipe after, together give you a perfect pre-coating workflow.

Buying the SONAX PROFILINE Prepare — pack size and recommendation

The SONAX PROFILINE Prepare comes in 400 ml (single bottle) as well as a 2-pack and a 3-pack. The 400 ml bottle covers plenty of full-car degreases at sensible dosing — since you spray onto the cloth and not the paint, the amount you use is easy to control. For detailers who coat cars regularly and run the panel wipe as a fixed workflow step, the 3-pack is the most economical option.

The Prepare is especially worth it for any detailer and reconditioning business laying down professional ceramic coatings who won't compromise on surface prep. For enthusiasts coating their own car with a polymer or ceramic sealant, the Prepare is your guarantee that the sealant bonds as well and as durably as it can. A common mistake when coating your own car is skipping the degreasing step — seal straight after washing and you risk a poor bond from polishing-oil or wax residue you can't see on the paint.

Bottom line, the Prepare is the link between paint correction and coating — a step that's easy to overlook, but one that decides the quality and longevity of the whole coating result. Build this step firmly into your detailing workflow and you'll be rewarded with clearly better and longer-lasting sealing results that mark the difference between a professional finish and one that only looks good on the surface.
