Koch Chemie Clay Bar Heavy
Aggressive Decontamination for Heavily Contaminated Surfaces
Koch Chemie Clay Bar Heavy is a high-strength detailing clay designed for deep surface decontamination prior to machine polishing or coating application.
Engineered for heavily contaminated, neglected or weathered paintwork, this aggressive-grade clay bar removes stubborn bonded contamination quickly and effectively - preparing the surface for proper paint correction.
This is not a maintenance clay. It is built for serious prep work.
Built for Heavy Contamination Removal
The Heavy Clay Bar is formulated to tackle deeply embedded contaminants including:
- Overspray
- Road tar
- Brake dust
- Industrial fallout
- Tree sap
- Rust bloom
- Heavy bonded grime
Its stronger abrasive composition allows it to cut through contamination faster than mild or medium clay options, making it ideal for older vehicles, commercial fleets and paintwork that has not been regularly maintained.
Designed for Polish Preparation
Due to its aggressive nature, Koch Chemie Clay Bar Heavy is intended for vehicles that will be machine polished afterwards.
It is best suited for:
- Paint correction preparation
- Coating installation prep
- Restoration details
- Severely neglected finishes
It is not recommended for new, soft or sensitive paintwork where correction is not planned.
Koch Chemie Clay Bar Heavy is a purpose-built solution for aggressive decontamination - ideal for professional detailers preparing paintwork for correction or ceramic coating installation.
