Whats the difference between the three cloth materials- Stayfast Cloth, Sonnedecke Cloth and German Cloth?
A. The Stayfast is a very good quality material. The Sonnedecke Cloth is Haartz version of the German Cloth and is a very good match- very high quality. It is argued that the Sonnedecke is a tighter weave than the German cloth and thus a better material. The Sonnedecke also has the dobby criss-cross style backing as the German- the Stayfast cloth does not have this. We would recommend the Sonnedecke cloth for any vehicle that came originally with the German Cloth because both materials are comparable, and the Sonnedecke is a fraction of the cost of the German cloth. The Stayfast we would recommend for all others.
