Have to be careful with paraffin wax with certain components.
If the wax is too hot it could overheat some parts, melt some plastics, or
ooze into a relay.
OTOH it can give quite a nice plume during the "smoke test".
I have used a mixture of paraffin wax melted with "Lionel-Train smoke
liquid" to coat transformers and pass transistors, gives a really graphic
indication when things are being pushed too hard.
