The Rag Company Ultra Clay Bar | Medium Grade Detailing Clay
The Ultra Clay Bar is The Rag Company's traditional detailing clay — a medium-grade synthetic polymer bar for pulling bonded contamination out of paint, glass, plastics and mouldings before polishing or coating.
Clay works mechanically: the lubricated bar glides over the surface and shears off anything standing proud of the clear coat — industrial fallout, brake dust that iron remover missed, paint overspray, tree sap. Removing it first means less polishing time, cleaner pads and a surface a coating can bond to.
Why we stock it
- A bar still gets into places a mitt cannot — badges, grille slats, door shuts.
- Knead to a fresh face as it loads; one bar does several cars.
- Pairs with any proper clay lubricant — Koch Chemie Clay Spray or P&S Paint Gloss both work well.
Specifications
- Synthetic polymer clay bar
- Grade: medium
- Use with clay lubricant only
How to use
- Wash and iron-decon first. Cut the bar in half and keep one half aside.
- Flatten to a patty, lubricate the panel generously and glide in straight lines with light pressure until the drag disappears.
- Wipe, inspect, fold the bar to a clean face and move on.
- Drop it on the ground and it is finished — bin it. Store in its tub with a spritz of lube.
Common questions
Bar or mitt? The mitt is faster on big panels; the bar is more precise and cheaper. For a coating prep we use both.
Will it remove swirls? No. Clay removes contamination sitting on the surface; swirls are in the clear coat and need polishing.
