I never do anything with mine, but I use a bit heavier wire
and have close spark gaps across the secondary and from
secondary to the ground side of the primary. Some of the
gaps look pretty bad after a few years.
I lose maybe one or two transformers a year and my area gets
hit by lighting several times a year.
I use metal composition resistors and haven't had one change
value yet, although I've got a few with the outer coating
