As a minimum, you do want to be sure to strip off any sodium salts that may
have been deposited from you or the distributor handling the acrylic tube.
Personally, I always use plastic gloves when handling or attached the sec
coil even after winding. This is a bit extreme, but easy to do, and you
certainly don't want any failures when showing off your nice coil to a
school group, etc.
Antonio is correct. Acrylic is an excellent HV insulator as long as someone
with slightly sweaty hands has not handled it. Detectives rely on this
principal to get fingerprints for their investigations.
