It seems reasonable to think so, but there are two problems.
1. Bare aluminum will have an extremely low surface resistance, way too low for any common Ohm meter. A conductance measurement would be required.
2. Ionization effects; most liquids ionize when current flows through them, resulting in all sorts of variations in a resistance or conductance measurement. A repeatable measurement is next to impossible unless a liquid that won't ionize is used. Mercury would work, but this isn't practical.
