SONAX PROFILINE GlassPolish (250 ml)
What it is: A silicone-free glass polishing compound designed to remove slight scratches, blinding, and etching on automotive glass. It uses a felt pad rotary approach with recommended speeds around 1000 rpm. Who it’s best for: Auto enthusiasts and professionals who want a silicone-free option that preserves clarity on car windows and avoids residue on seals. Why selected: This formula targets glazing imperfections while being gentle on glass and seals, reducing glare without introducing silicone-based contaminants. Caution: As with any rotary polishing, use light pressure and test on a small area first to avoid over-polishing delicate spots.
Key considerations:
- Silicone-free composition helps prevent new residue problems on glass and seals.
- Best for light scratches, minor etching, and slight blinding on car windows.
- Not a heavy-cut compound; use for preliminary improvement and follow with finer polishing if needed.

Buying Guide: Choosing The Right Glass Polishing Compound
What level of scratching is acceptable?
For light scratches, haze, and water spots, cerium oxide and diamond-based polishes provide effective results with controlled polishing. For deeper scratches, start with a coarser step or a more aggressive compound, then finish with a fine polish.
Which formula best fits automotive use?
Silicone-free formulations are preferred for automotive glass to minimize residue on seals and ensure long-term clarity. Cerium oxide and diamond-based products are common choices for cars, mirrors, and dashboards.
What equipment is needed?
Rotary or dual-action polishers, polishing pads or wool pads, and a clean, lint-free cloth are typical. Some products come with pads or brushes; others require separate tools.
Is a slurry necessary?
Some powders require mixing with water to form a slurry for even application. Others are ready-to-use pastes or liquids. Follow product-specific instructions to avoid over-polishing or staining.
What safety considerations apply?
Work in a well-ventilated area, wear eye protection, and avoid breathing fine powder. Use gloves if handling concentrated pastes and keep away from painted or plastic surfaces unless explicitly stated as safe.
What about maintenance after polishing?
Wipe surfaces with a clean microfiber towel, and if needed, apply a dedicated glass cleaner to remove any residual polish and restore clarity.
