Re: resealing "Old style" Lewmar Portlights
If you are dealing with plastic ports like the Becksons, then I would not try to re-bed them, its too much work to take a chance having to start over. With the Becksons, the drill is to buy a new unit and all new attachment fixtures, then bed carefully with a quality silicone as per Beckson instructions.
If dealing with good quality metal frames, I would try to clean and reuse.
