Shocking windshield a sign you need static wicks?

While in solid IMC last Sunday I reached toward the windscreen to see how
warm the defroster was and I got a quick series of static shocks without
actually touching anything. Under the same conditions I was still
receiving the VORs for the airway I was on and communicating with ATC with
no noticable drop in radio quality.

Is that a sign I need static wicks? If I'd been in the same conditions
for a longer period of time would my radio performance have degraded?
