Use in practice
Professional chemicals and polishing
AVP uses Koch-Chemie for paint correction, pre-cleaning, degreasing, hand washing and plastic care, as well as comparisons of cutting compounds and cleaning chemistry. Cut, finish quality, material compatibility, process stability and repeatability are assessed.
Cleaner, polish and protection must suit the material and the preceding and following work stages.
Frequently asked questions
H9.02 Heavy Cut is designed for stronger correction, F6.01 Fine Cut for medium defects and M3.02 Micro Cut for the finishing stage. AVP selects the combination only after inspecting the paint and completing a test spot, so no more cut than necessary is used.
Depending on concentration, Green Star is used for suitable intensive cleaning and degreasing tasks, while Allround Surface Cleaner is intended for controlled surface cleaning. Material, contamination and the following process determine the product and dilution.
NanoMagic Shampoo combines hand washing with a maintenance protection component. AVP first checks whether that effect suits the existing protection and maintenance plan instead of applying it indiscriminately over every protection system.
Top Star is aimed at suitable interior plastic surfaces, while Plast Star is intended for compatible exterior plastics. Both are applied thinly and evenly after material type, cleaning and the desired finish have been established.
Yes, provided the machine, pad, polish and paint are tested together and polishing residue does not interfere with the subsequent protection. AVP treats correction, degreasing and protection as separate controlled stages.
Technical context
Cutting compounds provide a high level of cut for stronger paint defects.
Read the explanationCut describes the corrective power of a polish or pad. Higher cut means stronger material removal, while lower cut is used for fine finishing work.
Read the explanationDegreasing removes oils and residues before protection is applied. It improves adhesion and prevents bonding failures.
Read the explanationPre-cleaning is the chemical or mechanical cleaning performed before polishing and protection.
