Hello Prad,
Thank you for sharing your detailed experience and your technical observations with our products! 😊
Our rosin has been specifically developed and produced in our French workshop to offer the best performance with Coruss hair.
It is important to apply it very lightly and progressively from the frog to the tip, as applying too much at once can actually cause the bow to slip or soap up.
If you feel there is an excess of dust or a loss of grip, we recommend cleaning the hair and only adding a tiny amount of rosin. It is important to add it only when you feel the hair needs it, rather than before every playing session.
Please feel free to contact our customer service so we can guide you through these adjustments and ensure you find the perfect sound balance. Have a great day!
The Coruss Team
