Pazon yes or no???

Of course you can do what you want but if electronics are working I clean them up and leave them alone. With good connections and good grounds I rarely have electronic problems. Actually over thousands of miles with my Commando from new with normal service the electronics gave me little trouble. Here in SF I had to clean connections once a year but I never really replaced anything, except when I broke a primary chain and cut some wires.
I'll let the other guys discuss the seal since it has been so long for me. I never had trouble with anything there either.
