Meguiar's Detailing Clay Bar (Aggressive) 7 oz — Removes Bonded Contaminants, Restores Glassy Finish

Meguiar's C2100 Mirror Glaze Detailing Clay is an aggressive, professional-grade clay bar that safely removes bonded contaminants to restore a smooth, glass-like finish on paint, glass, metal and plastic.

This 7 oz clay bar from Meguiar's is engineered to lift stubborn surface deposits — think paint overspray, industrial fallout, tar, bug residue and tree sap mist — without harming clear coats or single-stage paints when used with proper lubrication. Designed for quick, tactile results, the clay glides over a lubricated surface to pick up embedded grit and contamination that ordinary washing leaves behind, leaving the surface ready for polishing or coating.

How does this clay bar actually remove bonded contaminants?

The clay picks up microscopic particles by lightly adhering to them as you knead and glide the bar across a lubricated surface. It does not cut the paint like abrasive compounds; instead it pulls out bonded debris so the panel feels smooth to the touch. Follow-up polishing or protection is recommended for the best visual results.

• Works by mechanical adhesion to lift embedded particles
• Use with a dedicated lubricant such as M34 Final Inspection or D155 diluted 1:1
• Safe on paint, glass, metal and plastic when used correctly
• Prepares surface for polishing, sealant or wax

Is this aggressive clay safe for my car’s clear coat?

Yes — when used with adequate lubrication and gentle pressure this clay is non-abrasive to clear coats and single-stage paints. The aggressive formulation targets heavier contamination, but correct technique (kneading, folding, and replacing soiled clay) keeps the surface protected. If unsure, test on an inconspicuous area first.

• Non-abrasive action when lubricated
• Recommended to fold and refresh clay frequently
• Always use with M34 or D155 spray lubricants
• Do a small spot test on delicate or unknown finishes

What’s the right way to use Meguiar’s C2100 clay for best results?

Clean the panel first with regular shampoo, then spray a liberal amount of lubricant on the work area and glide the clay back and forth with light, even pressure. When the clay becomes discolored or feels gritty, fold and knead it to expose a clean surface. After claying, wipe the panel with a microfiber towel and continue with polishing or protection.

• Wash vehicle to remove loose dirt before claying
• Spray lubricant generously; do not use clay on a dry surface
• Work small sections, fold clay often to maintain cleanliness
• Finish with wipe-down and then polish or apply a sealant/wax

How much area will a 7 oz clay bar cover and how do I store it?

A 7 oz bar contains approximately 200 grams of clay and typically covers multiple vehicles depending on contamination level — heavier fallout reduces coverage. Store the clay in its reusable container to keep it clean and pliable; avoid extreme heat or contamination from grease. Proper storage extends usable life and ensures consistent performance.

• 200 grams of clay supplied in a reusable tub
• Expected coverage varies with condition and technique
• Keep in original container, away from high heat and solvents
• Replace when clay becomes overly contaminated or torn
