What resistance should I expect when testing capacitors?

Testing a 35V 1000µF capacitor shows a gradually increasing resistance that plateaus at around 9.85kΩ. Testing a 450WV 150µF capacitor shows a gradually increasing resistance that eventually exceeds the measurement capabilities of the multimeter (2MΩ). Is there any way to calculate what the resistance should be for a given capacitor?

Capacitors Insulation Resistance (Capacitor ir)

An understanding of the basic principles in­volved in this concept of "Insulation Resistance" should help to dispel this confusion. When a capacitor is charged from a DC energy source, an initial high current flows from the energy source into the capacitor. This current flow rapidly decreases toward zero as the capacitor absorbs it.
