We consider the stationary flow of Prandtl-Eyring fluids in two
dimensions. This model is a good approximation of perfect plasticity.
The corresponding potential is only slightly super linear. Thus, many
severe problems arise in the existence theory of weak solutions. These
problems are overcome by use of a divergence free Lipschitz
truncation. As a second application of this technique, we generalize
the concept of almost harmonic functions to the Stokes system.
