I was musing if there was a better way of igniting MX motors other than heating the bare nichrome bridge wire in contact with the propellant. Not a real problem for single motors but there are a couple of commercial MX cluster kits that were available plus I scratched a few of my own. An energetic igniter that would reliably light all motors in a cluster is the goal.
Off the shelf pyrogen dip kits make a sludge that results in a coating that would be too thick to fit the narrow throat of MX motors. So I decided to experiment with fingernail polish.

Will let this thoroughly dry before proceeding.
Want to evaluate the performance of the coating, not the solvent.
TBC.
