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