Im seriously considering replacing my ports with fixed lexan sheet , and I need to know the proper adhesive/sealer , I read that 4200/5200 , Boatlife is not advised .

The best sealer I''ve found for lexan IS THE boatLIFE--- Life Seal Sealant #1170. The stuff is real messy, but that''s what makes it stick so good. If you can manage to work it in without touching it with your fingers it''ll come out great. Even if you use rubber gloves, The stuff doesn''t want to come off of the gloves and gets everywhere. Once it cures it stays fairly soft, exactly what you want for a flexing hull/deck.
It works good on teak too....................._/)

The best product I have found for Lexan type lenses/windows is Dow Corning 795 construction adhesive.

The caveats are that it takes 7 days to set up... don''t be in a hurry, make sure you prep well, follow the instructions, clean up immediately.

This is what the "Pro''s" use when re-glazing ports, hatches, cabin lights.
