I'm getting ready to reassemble my Challenger's engine that's been re-honed and getting new rings & new bearings, etc. The piston skirts were a little scuffed up upon tear-down, but cleaned up nicely using a fine-grade Scotcbrite pad. Would there be any benefit to applying a spray-on dry graphite lubricant to the piston skirts as a break-in coating? Or would that be "stuff" that could potentially interfere w/ the rings seating properly as it wears off?
