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.

It has never caused me a problem as long as it is cleaned off and re-applied between checks if adjustment is needed. Rod

I don't wipe it off, I just brush it to erase the pattern for the next pattern check.
