To each his own.
I am a year round rider and have used silicone for years without ruining any ignition components. I use it on cars too and have not replaced a distributor cap or very many plug wires since I stated using it.
Once a year, I clean all the high voltage components to get the salt and crud off, then spray with silicone. Have not had a high voltage ignition problem since. What the silicone does is cause the water to bead instead of wetting the whole surface, this eliminates continuous conductive paths and prevents arcing.
Having had to clean off the laquer type sprays after they deteriorated, I won't use them again, but that does not mean they won't work for you.
