Efficient dipolar evaporation leads to the onset of quantum degeneracy in two-dimensional optical traps. When the electric field is used to tune excited molecular rotational states into degeneracy with the scattering threshold, we observe sharp collision resonances that give rise to three orders-of-magnitude modulation of the chemical reaction rate. Using this resonant shielding, we realize a long lifetime for a bulk molecular gas with tunable interactions.
