Some people do...I don't. Not Hylomar...but epoxy from what I have been told. But I would however sand all the corrosion off the seal mating surface. 600 grit smooth. I am sure more opinions to follow.

I have sanded the seating and sealing surfaces where the liners contact the block with 600 grit, but the narrow region between liners is pretty badly pitted. I need to do more sanding and cleaning. The old liners didn't leak, but they were stuck in really bad and took about 4 hours to get them free. I finally made a tool and pounded them out from the bottom. See picture below.
