Today in focus: car leather does not crack overnight, the finish dries out over weeks and then splits into fine lines. Go to leather care

From the blog: we measure 71 degrees on a black seat in the sun, and that is exactly where the cracking starts. Stop cracks before they start

From Friday: it turns wet, and the protection has to be on before that so the water runs off instead of clinging. Go to paint sealants

This week: Wednesday is forecast at 34 degrees, so the interior is a job for early morning. Go to interior care

Best seller: the COLOURLOCK „Pol Star“ concentrate handles fabric, leather and Alcantara out of one bottle. Go to Pol Star

Paint protection: the Soft99 Fusso Coat Light lays down a hard wax layer that rain runs off as beads. Go to Fusso Coat

Talk to us: send a photo of your leather over WhatsApp and we will tell you whether care is enough or it needs repair. Start a chat

Digital advice: our shopping assistant gets you to the right product in a few questions. Open the assistant

Customer support: questions about order, delivery or returns are answered in our help centre around the clock. Go to the help centre

Buyer protection: every order runs through Trusted Shops, so the reviews there are verified and independent. Read the reviews

Koch-Chemie Spray Head "Opus" (28/410)

The Koch-Chemie spray head "Opus" (28/410) is a solid, no-nonsense head built for the 500ml and 750ml bottles from Koch-Chemie. Worth knowing: you don't need to order it separately, because it always comes in the box with those products.

  • Perfect fit: threads onto every 500 ml and 750 ml Koch-Chemie bottle.
  • Easy to work with: lays the product down evenly, so you can work precisely.
  • Built to last: takes daily use in car care without giving up.

What the "Opus" spray head fits

The "Opus" spray head (28/410) is made for the usual Koch-Chemie bottles in 500 ml and 750 ml. It sits tight and lets you lay product down cleanly, with nothing running down the side of the bottle.

Versatile in use

Fine mist or a targeted jet — you pick, depending on the job. That makes it handy whether you are laying down cleaners, sealants or any other liquid.

Durability and quality

The "Opus" head is built for the long haul. Even under heavy use it keeps spraying the way it should, which makes it an easy companion for anyone working on cars every day.
