if it were me ?, I would look for some kinda large rubber open doughnut thick enough to place between the skid plate and drain plug, this way no oil will drip on the skid plate.
not solid enough, oil will seep right past it once it soaks a bit of oil up.I ordered one of these:

I may have to cut the hole a little larger, but it might work. Worth a try.
