Rusty Spark Plugs

[larrendeuce]

I run Autolite 25's. I change them once a year at the most, more often if I feel like it. The black oxide finish doesn't hold up well. They start to look rusty after a couple of weeks. Does anyone run a similar plug that holds up better? The electrode and ground strap are fine, but everything outside the combustion chamber rusts up.

Very common on spark plugs. Try coating them with some rustoleum to keep the new look.
