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

Degrease and Inspect the Paint Before Sealing — SONAX PROFILINE Prepare

What does SONAX PROFILINE Prepare do? This cleaning and inspection spray degreases paint surfaces without leaving any residue before applying sealants and ceramic coatings — and at the same time makes remaining polishing oils and silicone residues visible through its inspection effect.

Every professional sealant, ceramic coating, and paint protection film application begins with an indispensable step: complete surface degreasing. Oils, silicones, polishing residues, and release agents are invisible contaminants that severely impair the chemical adhesion of sealants — an undegreased surface leads to uneven bonding, shortened durability, and visible imperfections. SONAX PROFILINE Prepare is the specialized degreasing and inspection spray for this critical step: fast-acting, residue-free, and simultaneously usable as an inspection spray that makes any remaining impurities visible through light refraction.

• Residue-free degreasing before sealing and coating. Polishing oils, silicones, and other release agents are hydrophobic substances that adhere to the paint unless specifically removed. Prepare dissolves these contaminants and lifts them off the paint when wiped — without leaving any residues that could interfere with the subsequent sealant. A thoroughly degreased surface is a prerequisite for polymer or ceramic sealants to achieve their full adhesion and durability.
• Inspection effect makes contaminants visible. In addition to its cleaning action, Prepare spray has an important inspection function: When the spray is applied to the surface, areas with oil residues or polishing oil show a characteristic streaking of the spray film. Areas without contaminants, however, show an even wetting pattern. This visual cue allows the user to re-clean precisely where needed before applying the sealant — a quality assurance measure indispensable in professional detailing.
• As a preparation spray and panel wipe in the detailing workflow. Prepare is suitable both as a surface degreaser before coating and as a panel wipe after paint correction (polishing) — to completely remove polishing oil residues before sealing. This means the product can be used not only in the sealing process but also as an integral step in the complete reconditioning workflow (polishing → panel wipe → coating).

Practical tip from Detailing1: Always use Prepare immediately before applying the sealant or coating — not hours beforehand, as dust and environmental contaminants can immediately resettle on the cleaned surface. Apply the spray to a clean, lint-free microfiber cloth (do not spray directly onto the paint to prevent uncontrolled spreading), wipe the area to be sealed, and immediately switch to the dry side of the cloth to wipe off. Work in a garage or enclosed spaces without drafts to avoid recontamination. Immediately after Prepare, apply SONAX PROFILINE PolymerNetShield or a ceramic coating.

Degreaser and Inspection Spray — How Prepare Prepares Surfaces for Coatings

The action of the degreaser and inspection spray is based on fast-evaporating solvents that dissolve fats, oils, and silicone residues on the paint surface and lift them off the paint with the wiping cloth. Unlike aqueous cleaners, these solvents do not leave a moisture film on the surface after evaporation — the evaporation is complete and residue-free, which provides the ideal basis for the immediate subsequent coating.

Its particular value lies in its dual function: While the spray cleans, the visual inspection effect shows the user where contaminants are still present. This effect is based on the different surface tension of contaminated and clean paint: On degreased paint, the spray spreads evenly as a fine film; on contaminated paint, it contracts and shows characteristic craters or beads. This effect is particularly important if the surface to be coated was not completely oil-free after polishing — even small amounts of polishing oil can permanently impair the adhesion of a ceramic sealant locally.

In professional vehicle detailing, the panel wipe step with a degreaser like Prepare is a quality standard that no serious detailer omits: Ceramic sealants like SONAX PROFILINE HybridCoating "CC One" bond chemically to the clear coat — a layer of grease blocking this bonding area reduces adhesion quality and can lead to detachment or uneven protection after months. The few minutes required for a thorough degreasing step pay off in significantly improved durability and uniformity of the coating.

Applying Prepare Correctly — The Panel Wipe Workflow Step-by-Step

Applying the panel wipe spray is simple, but the quality of execution is crucial for the final coating result. Preparation: The vehicle must be completely washed and dried before the degreasing step — Prepare is not a cleaner for dirt or dust, but exclusively for oily and silicone-containing residues on an already washed, dry surface. Water and dirt residues on the surface prevent the degreasing effect and leave streaks.

Application: The microfiber cloth for Prepare should be new or freshly washed — a cloth that has already absorbed polishing oil will transfer it back onto the paint surface during wiping, counteracting the degreasing effect. Spray Prepare onto the cloth (not directly onto the paint) to control the amount of solvent and prevent uncontrolled action on sensitive paint areas. Wipe over the surface with light to medium pressure — the inspection effect is immediately visible: Even wetting indicates a clean surface, uneven distribution shows oil residues. Rework until even wetting is visible.

Removal: Immediately after wiping with the damp side of the cloth, wipe off with the dry side or a second clean cloth before the solvent fully evaporates. This removes the dissolved fats and oils from the paint and prevents them from being rubbed back onto the surface. Immediately thereafter, apply the chosen sealant product — without pause, as the degreased paint is now maximally receptive to the coating chemistry. On large vehicles, work section by section: Prepare and then immediately seal, section by section.

Areas of Application — When Degreasing Before Sealing is Indispensable

The degreaser spray is indispensable in several situations within the detailing workflow. The most common application is the panel wipe after paint correction: Every polish releases polishing oil, which acts as a lubricant and abrasive carrier between the pad and the paint. After polishing, this oil film remains on the paint — a uniform, fine, but harmful layer for the adhesion of sealants. Prepare completely removes this film and prepares the freshly polished clear coat for immediate sealing.

The second common area of use is preparation for paint protection films (PPF): Protective films adhere to the paint with adhesive layers and require an absolutely oil- and silicone-free surface for optimal adhesion and edge sealing. Even minor silicone spots under the film can lead to air bubbles, incomplete adhesion, and later detachment — a flawless degreasing step with Prepare is therefore a special professional standard for PPF applications. Degreasing is also important when re-sealing vehicles that have previously been treated with wax or polymer products: Old wax and polymer residues on the paint can noticeably impair the adhesion of a ceramic sealant in those areas.

Prepare is also valuable for quality control after polishing, regardless of the subsequent sealing: The inspection effect shows whether the polishing was carried out evenly across the entire surface, or whether areas with polishing residues indicate spots that have not yet been worked on. Thus, Prepare simultaneously serves as a quality assurance tool that reveals gaps in the polishing work, thereby preventing errors in the final sealing before they are encapsulated.

Prepare Compared — Degreasers and IPA Solutions for Paint Pre-treatment

In professional detailing, several products are used as degreasers and panel wipes. Isopropyl alcohol (IPA) in diluted form (typically 10–20% in water) is a classic panel wipe that is inexpensive and widely available — its degreasing effect is good, but the inspection function is absent. Those who degrease with IPA must rely on other indicators to assess the completeness of the degreasing step. Prepare offers a clear advantage here: The visual inspection effect gives the user immediate feedback on the quality of the degreasing step.

Compared to universal degreasers or solvent-based cleaners, Prepare positions itself as a product that is more compatible with paint and less aggressive to surfaces — not every solvent can be used without problems on sensitive clear coats, fresh multi-layer paint finishes, or coated surfaces. Prepare is specially formulated for use on vehicle paint and is safe on all common clear coat qualities. On fresh factory new paint finishes or repair paints, a short test application should be made to ensure compatibility — especially on very freshly applied clear coat that has not yet fully cured.

Compared to brand-independent degreasers, PROFILINE Prepare has the advantage of system compatibility: It is matched to the PROFILINE sealant line and leaves no residues that would be incompatible with PROFILINE coating products. For detailers who use a completely coordinated product system, this is an important quality factor — systematic compatibility reduces risks and makes results more reproducible. The SONAX PROFILINE PerfectFinish "4/6" as a preceding finish polish and Prepare as a panel wipe afterwards together result in a perfect pre-coating workflow.

Buying SONAX PROFILINE Prepare — Container Size and Recommendation

The SONAX PROFILINE Prepare is available in 400 ml (single bottle) as well as in 2- and 3-piece sets. The 400 ml bottle is sufficient for many vehicle degreasing jobs with proper dosage — since the spray is applied to the cloth and not to the paint, the product quantity is easily controllable. For detailers who regularly coat vehicles and perform panel wipes as a fixed workflow step, the 3-piece set is the most economical option.

Prepare is particularly recommended for all detailers and reconditioning businesses who apply professional ceramic sealants and do not want to compromise on surface preparation. Even for enthusiasts who coat their own vehicles with a polymer or ceramic sealant themselves, Prepare guarantees that the sealant adheres as well and as durably as possible. A common mistake when self-coating is omitting the degreasing step — those who seal directly after washing risk poor adhesion due to invisible polishing oil or wax residues on the paint.

In summary, Prepare is the connecting link between paint correction and coating — a step that is easily overlooked but determines the quality and longevity of the entire coating result. Those who consistently integrate this step into their detailing workflow will be rewarded with significantly better and more durable sealing results that make the difference between a professional and merely superficially good result.
