98 Expedition 5.4.
I cleaned the water pump surface in preparation for a new pump install. First wire brush, then green scotchbrite pad. Came really clean, but there are some areas of slight oxidation remaining as seen in the picture below.
Is this anything to be concerned about, or should this be no problem with leaking? O-ring seal on the water pump.
I am debating on a light coat of Hylotyte red on the surface to bridge some of the imperfections, although that might make installation of the o-ring bind with the added friction. Also thinking a Dremel polish as well, but that might do more harm than good
