Disclosed herein is a gauge for slurry coating thickness determination. The gauge includes a body and at least three probes extending from the body. The at least three probes provide a go-no-go indicator including a first demarcation that defines a minimum slurry coating thickness and a second demarcation that defines a maximum slurry coating thickness. A minimum no-go region is defined between the first demarcation and a probe tip, a maximum no-go region is defined between the second demarcation and the body, and a go region is defined between the first demarcation and the second demarcation.
