It uses Flex-Clay Technology to remove embedded contaminants such as overspray and pollution across paintwork, glass, plastic, and metal surfaces.

The Medium Duty Clay Bar targets tougher pollutants that light-duty clays may miss. It’s ideal for vehicles with older finishes or heavy contamination, helping to restore a smooth surface. This choice is best for enthusiasts who perform periodic decontamination. A limitation is that it’s more aggressive, so care should be taken on softer paints or clear coats.

Buying Guide: How To Choose The Right Heavy-Duty Clay Bar
- Surface type and finish: For delicate paints or clear coats, start with milder clays and test on a small area first.
- Contaminant severity: Heavy-duty clays excel at embedded fallout; lighter options suit surface-level contamination.
- Lubricant compatibility: Always use a dedicated detailing lubricant to reduce friction and prevent marring.
- Application scope: Consider whether you’re detailing a single vehicle or multiple vehicles; multi-pack sets offer better value for larger projects.
- Surface compatibility: Most clays work on paint, glass, plastic, and metal, but always verify compatibility with your specific surface.
- Risk awareness: Aggressive clays can scratch if used improperly; use light pressure and consistent lubrication.
