We Say
Finish Spray Exterior is often seen as just a quick detailer, but in reality it plays a much more useful role at the end of the wash or correction process.
As well as removing light dust, fingerprints and fresh residues, FSE is particularly effective at breaking down light water spots and mineral residue left behind after washing — something that’s especially noticeable in hard water areas. Used correctly, it helps clean up faint limescale marks before they have a chance to bond properly to the surface.
It also excels as an inspection spray. It wipes cleanly without smearing, even on darker paints, making it ideal for checking your work between polishing stages or refining the finish before delivery.
For us, FSE is the final refinement step. If you want a fast, streak-free way to sharpen gloss, deal with light water spotting and leave paint looking exactly as it should, this is a product we reach for regularly.
Key Features
Description
Koch Chemie Finish Spray Exterior (FSE) is a fast-acting finishing spray designed for the final refinement of exterior surfaces. It safely removes light dust, fingerprints and fresh residues while enhancing gloss and surface slickness.
The formulation is designed to wipe off easily without streaking, making it particularly suitable for dark or sensitive paint finishes. FSE can be used after washing, during the polishing process for inspection, or as a final wipe-down before handing the vehicle back.
Typical applications:
✓ Final wipe-down after washing
✓ Removing polish residue during inspection
✓ Light dust and fingerprint removal
✓ Enhancing gloss before delivery
FSE provides a small amount of short-term protection, but is best viewed as a finishing and inspection aid rather than a standalone protective product.
