Needing To Add Resistance Coating To Aluminum/Titanium

These are for an assembly that requires a circuit.

Small Aluminum Disk - Roughly .9 ohms of Resistance
Small Titanium Disk - Roughly 1.1/1.2 ohms of Resistance

I am looking for a coating/finish that we can use to bump either one of the above up to about 1.5-1.7 ohms of resistance.

Looked in to Clear/Yellow/Black Zinc Chromate. Would any of these work?

Are there any coatings that will keep electrical conductivity, but add resistance to the piece in question?
