I don’t think I’d use epoxy on the coils. It may cause problems down the road (or lake).
There is a special product, kind of an electrical varnish that’s an electrical insulator.
I can’t remember the name now, but it could be used on suspect areas if needed.
They’re probably okay as is, but a coil tester, using the probe, would tell for sure.
I rather replace antique condensers than presume the old ones don’t have leakage
or are still within specs. Often when I check the capacitance on the old condensers,
they read higher than what they are suppose to. The electronic capacitors seem
to bring new life to old motors.
According to the condenser charts, the Lightfours, depending on year made, use
either a .1 or .2 mfd condenser.
