Maximum Paint Correction. Professional Results.

When paintwork has suffered years of neglect, light polishing simply isn't enough.

Auto Glanz H3 is a professional-grade heavy cut polish engineered to rapidly remove severe paint defects, heavy oxidation, swirl marks and sanding marks while maintaining excellent user control and finish quality. Combining advanced abrasive technology with innovative lubricating polymers, H3 delivers impressive correction with a clean, dust-free working experience.

Whether you're restoring heavily weathered paint or carrying out a full paint correction, H3 provides the cutting performance needed to transform tired finishes.

Powerful Correction with Outstanding Control

H3 combines both friable (diminishing) and non-friable abrasives to deliver the perfect balance of aggressive correction and controlled refinement.

The initial cutting action quickly removes oxidation, sanding marks and deeper imperfections before the diminishing abrasives begin refining the finish. Advanced lubricating polymers increase pad glide, improve abrasive mobilisation and reduce friction, helping achieve faster correction with minimal dusting and a cleaner finish.

When paired with the appropriate polishing pad, H3 is capable of removing sanding marks up to P2000 grit, making it the ideal first stage in a multi-stage correction process.

Suitable For

H3 is ideal for:

• Heavy paint correction
• Removing oxidation
• Correcting deep swirl marks
• Reducing the appearance of deeper scratches
• Removing up to P2000 grit sanding marks
• Restoring neglected paintwork
• Preparing paint for refining with M3 or F3

How To Use

1. Apply 2–4 small drops of H3 to a suitable heavy cutting polishing pad.

2. Work a section approximately 2ft² using slow, overlapping passes.

3. Begin with moderate pressure to maximise correction.

4. Continue polishing until the compound becomes clear and the defects have been significantly reduced.

5. Wipe away any remaining residue using a clean, plush microfibre cloth.

6. Follow with M3 Medium Cut Polish or F3 Fine Cut Polish where required to further refine the finish.

Always perform a test spot to determine the least aggressive pad and polish combination required.
