I would replace it. They don't cost much and there's no point playing
around with a PL-259 that has already arced over. It will do it again
regardless of how well you think you have cleaned/restored it. Replace
the barrel too to be on the safe side.
Always use the highest quality connectors you can afford because you
don't want to save a small amount on a point of failure that will stop
you from operating all that expensive gear and which will prevent you
from doing what you set up your station to do in the first place, like
contest.

I've discovered that one of the PL-259s on a pre-made RG-8X cable
shows carbon tracks inside and arcs when I try to use it - I run full
power through the junction on 40M and lower bands. Am I right to
assume that I need to replace the connector, or is it feasible to
clean up and reuse? Should I toss the mating barrel connector as
well? I don't mind replacing, but with ARRL DX next weekend and Radio
Shack out of business, time is a consideration.
