Prussian blue

[Terry, NJ]

Dykem is a great layout fluid but it is actually too thick for a high spot "paint".
It tends to flake off or bunch up in tight (Say, .001 clearance) places. Prussion High spot blue must be nearly all wiped off to avoid having an indication of a contact where none exists. It must be thinly applied.
