  Screening mechanisms for a three-form field around a dense source such as the
Sun are investigated. Working with the dual vector, we can obtain a thin-shell
where field interactions are short range. The field outside the source adopts
the configuration of a dipole which is a manifestly distinct behaviour from the
one obtained with a scalar field or even a previously proposed vector field
model. We identify the region of parameter space where this model satisfies
present solar system tests.
