  We consider 4-dimensional $\mathcal{N} = 2$ superconformal quiver theories
with $SU(N)^M$ gauge group and bi-fundamental matter and we evaluate
correlation functions of $n$ coincident Wilson loops in the planar limit of the
theory. Exploiting specific untwisted/twisted combinations of these operators
and using supersymmetric localization, we are able to resum the whole
perturbative expansion and find exact expressions for these correlators that
are valid for all values of the 't Hooft coupling. Moreover, we analytically
derive the leading strong coupling behaviour of the correlators, showing that
they obey a remarkable simple rule. Our analysis is complemented by numerical
checks based on a Pad\'e resummation of the perturbative series.
