I used Plasti Dip to coat the wire.

 Maybe substituting a terminal

nope.

Max,

What did you treat your secondary with? You should coat it with many layers
of varathane or better is that two part epoxy paint, Chip swears by this
stuff so you should ask him about where you can get it. Personally I do not
use that but I have many coats of varnish on my secondary and the few top
turns including the air wound part is coated with Plasti Dip. The Plasti Dip
does away with corona leaking out the coil. Also read the post about primary
coils, that will help you with the coupling. Anything further from me would
be speculation, I now leave it in the hands of the experts.

Good luck!

                                       Regards,
