Description
Gloss, Protection, and Ease of Maintenance
Würth Stjarna Wünderseal is a premium rinse aid designed to deliver instant hydrophobic protection and high gloss after washing. By promoting rapid water run-off, it reduces drying time, minimises spotting, and leaves a slick surface that resists dirt adhesion.
Customisable Finish
With dilution ratios ranging from 1:1 for maximum gloss to 1:10 for economy use, Wünderseal adapts to your needs — whether you are preparing a vehicle for presentation or maintaining a fleet.
Enhanced Detailing Results
For the most uniform finish, buffing panels after rinsing ensures even coating distribution and improved visual impact.
