Re: Exercising older thru-hulls
OK, I think I'd be a little leery using Kroil or other penetrating oils -- many of ball valves have either teflon or PTFE surrounding the ball in the housing for a smooth interface with the stainless or chromed ball. I honestly don't know whether the penetranting fluids would do damage to the teflon/PTFE or not, but you never know -- it's certainly something to check thoroughly ahead of time.
You might want to try heating the housing gently with a heat gun...
