Product Description

Koch Chemie Finish Spray Exterior (FSE) is a premium all-round exterior detailing spray that cleans, maintains, and protects paint, glass, and exterior plastics in a single easy step. The advanced formula quickly dissolves limescale deposits, water spots, light contamination, and road film without streaking or leaving residue behind. The result is a smooth, brilliant high-gloss finish with restored color depth that looks freshly detailed every time.

Apply it after washing as a finishing spray to enhance gloss and add a layer of protection against new dirt and contamination. Works on all exterior surfaces including painted panels, glass, chrome, and plastic trim. Easy spray-on, wipe-off application makes it fast and efficient for professional detailers doing full exterior details and maintenance washes alike.

If you are looking for the best exterior detailing spray for professional car care, a Koch Chemie finish spray that cleans and protects in one step, or a quick exterior maintenance product that delivers show-quality results between full details, Koch Chemie FSE is a benchmark spray used in professional detailing shops worldwide. Available in 1L and 5L.

Koch Chemie FSE (Finish Spray Exterior) Usage

Finish Spray Exterior (FSE) is Koch Chemie's quick detailer and drying aid — spray-on/wipe-off exterior dressing that adds slickness and gloss. Works on wet or dry paint.

  • Wet application (drying aid): Mist onto rinsed panel, wipe with drying towel. Dries and dresses in one pass.
  • Dry application (quick detail): Mist onto cool, clean panel, wipe with clean microfiber.
  • Frequency: Every wash, or between washes as a quick refresh.

Frequently Asked Questions

Is Koch Chemie FSE a drying aid or a quick detailer?

Both. Sprayed onto wet paint during the drying stage, it's a drying aid (helps water release and adds slickness). Sprayed onto dry, dusty paint between washes, it's a quick detailer. Same bottle, two modes.

Can I use Koch Chemie FSE on ceramic coatings?

Yes — FSE is safe on ceramic-coated paint and is frequently used by shops as a weekly maintenance spray to refresh hydrophobics. Doesn't strip coatings.

Koch Chemie FSE vs Protector Wax — which should I use after a wash?

FSE is lighter — slickness and immediate gloss, minimal protection layer. Protector Wax is heavier — adds actual 2-3 month sealant durability. Use FSE between washes as a quick refresher. Use Protector Wax once every few washes as a proper top-up.
