Do I need a clay lubricant to use this?

Yes. Clay bars work best with a slip agent—soap, dedicated clay lube, or detailing spray. Without it, you risk dragging and marring the surface. Mix a few drops of car wash soap into a spray bottle of water if you don't have clay lubricant on hand.

Will this scratch my paint or clear coat?

No. The formula is abrasive-free and designed to lift contaminants without cutting or hazing. The key is keeping the surface wet with lubricant while you work—dry clay on paint will cause damage.

How do I know when the bar needs to be replaced?

Once it becomes crumbly, won't hold together, or stops picking up contaminants cleanly, it's time for a fresh bar. Most single bars handle 3–5 full-car details before wearing out, depending on how dirty the paint is.
