German Sonnenland Canvas is the original German made canvas used in many Mercedes, Porsche, BMW and other convertibles. It's general construction is very similar to the other two canvases. It is hard to tell the surfaces apart among the three. But the manufacturing specifications make this the longest lasting top. There is an approximate twenty percent greater wear rating for Sonnenland than for Haartz Stayfast. Some of this is due to the abrasion resistance of the exterior canvas. This is a factor in certain tops where the framework design tends to produce friction between the top's surface and the car's hardware. (It is a well known 'trade secret' that the Haartz Division of Glen Raven Mills purchased the Sonnenland factory.)

Sonnendeck Canvas (also called 'Twillfast') is an American made canvas, true double texture topping like the Haartz Stayfast. Many purists who own Mercedes and other German cars want to see the particular German weave (that is called "dobby weave") when they look up inside the car. Haartz Stayfast canvas has a plain (unwoven) inner lining. So for Porsche, Mercedes and BMW owners who will spend a little more in order to see that "dobby" weave we offer a fabric called Sonnendeck (in addition to the original German Sonnenland or Happich canvas. The wear rating of Sonnendeck is also greater than for Haartz, by perhaps 10%. This is due to the slightly heavier inner lining and subtle bonding specification differences.

Haartz Stayfast Canvas has a canvas outer layer and a preshrunk cotton inner layer. The two are bonded with and separated by a butyl rubber core. It is this core that makes the fabric last a very long time, with both better static and dynamic wear ratings than vinyl toppings. Haartz Stayfast is the American substitute for the German canvases used in Mercedes, Porsche, BMW, some models of Mustang and Lebaron and others. Canvas is widely regarded as "richer looking" than vinyl. It is a little harder to clean. The inside of the top is pre-shrunk cotton. The inner lining is usually black.

CONVERTIBLE TOP FABRICS
Almost all manufacturers use Haartz fabrics. They may specify "heaviest weight" or "original replacement" in ways that seem reassuring. But they do not really tell the whole story. Please bear in mind that two things dominate, by far, the quality issue: (a) the manufacturing quality control in the factory that makes the top and (b) the care and thoroughness of the installation. There is a trade-off in weight: heavier is better for resisting tear through, but lighter is better for flexibility and abrasion from within that may arise from movement. Almost all our tops are a flexible medium density (36 oz.) fabric. Heavier is not better in most cases. Where it is, because of the top design, we will say so and the top will be made of the heavier vinyl.
