A technical guide on the differences between abrasive pastes, polishes, and protectants to achieve a flawless finish
Abrasive pastes are essential tools for removing significant defects on paint, such as deep scratches, sanding marks, and advanced oxidation.
Composition and mechanism of action
Abrasive pastes contain calibrated abrasive particles, often aluminum oxides or silicates, with a specific grain size that determines the degree of abrasiveness. They act through mechanical abrasion of the clear coat layer, removing a minimal amount of material to level the surface and eliminate defects.
Professional application
Preliminary analysis: assess the thickness of the clear coat with a thickness gauge (feeler gauge) to make sure there is sufficient material for correction.
Instrumentation: use rotary or orbital polishers with foam or wool pads, depending on the level of cut desired.
Technique: apply with controlled movements, maintaining a constant speed and monitoring surface temperature to avoid overheating.
Protectives, formerly called sealants, are products designed to create a chemical barrier on the painted surface, protecting it from environmental contaminants and chemical agents.
Types of protectants
Synthetic Polymerics: offer long-lasting protection by synthetic molecules that bind to the paint.
Ceramics (Nano Coating): use silicon- or titanium-based compounds to form an extremely durable and hydrophobic layer.
Hybrids: combine organic and inorganic elements for a balance of ease of use and durability.
Specialized application
Surface preparation: essential to ensure that the surface is free of oils and residues using degreasing products or isopropyl alcohol.
Application method: strictly follow the directions on the data sheets, often requiring specific application times and controlled environmental conditions.
Curing: some protectants require a cure period to achieve maximum performance, during which time the car must be protected from weathering.
For effective professional intervention, an accurate diagnosis of the paint condition and the specific needs of the vehicle is essential.
Assessment tools
Thickness gauge: to measure the thickness of paint and clear coat layers.
Inspection lamps: for highlighting defects not visible to the naked eye under normal lighting conditions.
Hand-held microscope: for detailed analysis of scratches and contamination.
Determining the operating process.
Level of correction needed: determine if light polishes are sufficient or if aggressive correction with abrasive pastes is needed.
Appropriate type of protective: based on the intended use of the vehicle (e.g., exposure to severe environmental conditions) and the customer's expectations for durability and maintenance.
Integration of products into the detailing process.
For optimal results, it is advisable to integrate the use of abrasive pastes, polishes, and protectants in a sequential and coordinated process.
Operating protocol
Chemical and mechanical decontamination:
Removal of ferrous contaminants, resin, tar and other surface impurities.
Correction with abrasive pastes:
Removal of severe defects, using the appropriate product and pad.
Polishing with polish:
Refining the surface for optimum gloss.
Pre-protective cleaning:
Use of appropriate products to remove oils and polishing residues.
Protective application:
Even distribution of product according to specific techniques (e.g., cross-linking for ceramic coatings).
Post-application care:
Adherence to cure times and protection of the car from external agents.
Technical considerations
Compatibility of products: ensure that the products used are compatible with each other to avoid unwanted reactions.
Environmental conditions: temperature and humidity affect processing and effectiveness of products; operate in controlled environments whenever possible.
Certain car brands are strongly associated with certain colours. For example, Ferrari is synonymous with red, a colour that represents speed, passion and performance. Porsche, on the other hand, is often associated with black and white, colours that reflect elegance and purity of design. Lamborghini is famous for its cars in bright colours such as yellow and orange, representing the boldness and sportiness of the brand. These colour choices are not random: they are an integral part of branding and help define the brand's identity on the global market.
