  We show that for a C*-algebra A and a discrete group G with an action of G on
A, the reduced crossed product C*-algebra possesses a natural generalization of
the convolution product, which we suggest should be named the Hadamard product.
  We show that this product has a natural Stinespring representation and we
lift some known results on block Schur products to this setting, but we also
show that the block Schur product is a special case of the Hadamard product in
a crossed product algebra.
