Overview
This is a 4-pack of 100g detailing clay bars meant to lift bonded surface contamination off paint and glass before waxing or sealing, not a wash-and-dry product on its own.
Clay bars work by physically shearing off contaminants the paint has bonded to, such as tree sap, overspray, water spots and mineral deposits, that a wash alone will not remove. Fitosy positions this one for a wide range of surfaces beyond paint, including glass, chrome, wheels and carbon fiber, and each bar can be reused multiple times by folding a dirty side inward. No customer reviews are attached to this listing.
- 4 pack, 100g bars, 400g total
- Rated for paint, glass, chrome, wheels and carbon fiber
- Lifts tree sap, overspray, water spots and mineral deposits
- Reusable by folding to an unused side
Who it's for
Car owners doing a pre-wax or pre-coating detail who have visible bonded contamination such as tree sap, overspray or water spots. Not needed for a routine wash with no surface contamination to remove.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4 bars per pack cover multiple detailing sessions
- Works on glass, chrome, wheels and carbon fiber
- Reusable by folding to a clean face
- Removes bonded contamination a wash alone will not lift
- Requires a wet, lubricated surface, cannot be used dry
- Reuse depends on keeping clay free of grit
- No standalone cleaning effect without a wash step first
Performance notes
Clay only works on a wet, lubricated surface, so the panel needs to be soaked with water or a dedicated clay lubricant before the bar is kneaded flat and dragged across it; used dry, clay can mar rather than clean paint. Each bar can be folded to a fresh side and reused as long as it stays free of grit that could scratch the surface.
