Product Description

Gyeon Q²M Prep Pre-Cleaner is an essential step in preparing your paint for a ceramic coating. It reliably removes oil, grease, wax, and polish residues that could affect the adhesion of the coating – for maximum performance and durability.

Unlike conventional IPA or glass cleaners, Q²M Prep offers a lubricating, anti-static formula that safely dissolves and picks up polish residues without causing scratches. This creates a clean, smooth, and dust-free surface on which the sealant can adhere optimally.

Key Features

  • Reliably removes oil, grease & polish residues
  • Ensures optimal adhesion of coatings
  • Anti-static additives prevent dust accumulation
  • Gentle, streak-free application without IPA disadvantages
  • Essential for perfect paint preparation

Suitable For

  • Preparation of painted surfaces before ceramic sealants
  • Removal of polish, wax & oil residues
  • Optimizing the adhesion of protective layers

How To Use

  1. Clean the surface thoroughly.
  2. Spray Q²M Prep evenly onto the area (not on hot paint).
  3. Allow to dwell briefly.
  4. Wipe off with a clean, lint-free Microfibre Towel (e.g., PolishWipe EVO).
  5. Change cloth sides regularly until the surface is residue-free.

What's Included

  • 1 × Gyeon Q²M Prep Pre-Cleaner – 500 ml

Summary: With Gyeon Q²M Prep, you prepare your paint surface perfectly and professionally for the sealant – for maximum adhesion, performance, and protection.
