8 pages; v2 small changes<br/>We approach Gathmann's virtual pushforward property from the perspective of bivariant intersection theory, extend a virtual pushforward result of Manolache, and use our extension to deduce a result of Gathmann relating relative and rubber GW invariants of a $P^1$ bundle with invariants of its base.<br/>
