  We apply integral representations for $(0,q)$-forms, $q\ge1$, on non-smooth
strictly pseudoconvex domains, the Henkin-Leiterer domains, to derive weighted
$C^k$ estimates for a given $(0,q)$-form, $f$, in terms of $C^k$ norms of
$\mdbar f$, and $\mdbar^{\ast} f$. The weights are powers of the gradient of
the defining function of the domain.
