Gtechniq W9 Water Spot Remover is a concentrated formula which is 100% coating safe.

Unlike standard single mechanism water spot removers, W9 has a three mechanism approach to removal: 1) it dissolves and removes salts; 2) it traps metal ions, which are commonly found in tap water; and 3) it removes silica scale which is traditionally very tough to remove.

Hard water spots and silica scale will disappear from the exterior surface with ease. The formula also works well on glass, where watermarks can be exceptionally hard to remove.

Use Gtechniq W9 Water Spot Remover on ALL paint types, including matte finishes.
