Just did all of mine. After hours of wrestling to get the previous "bedding" off - it's butyl for me.
Make sure you allow for squeeze out (photo below) for a day or two before fully tightening down and trimming off the excess.
While they are out, it's a good opportunity to epoxy-seal the inner bulkhead/core to make it fully water-tight. (photo)
I just finished repairing/replacing some interior teak panels in my galley and dining area where the old portlights had leaked and damaged it. I'm getting ready to install the new portlights and noticed that there are voids in some areas of the bulkhead/core. I'm planning to use epoxy to fill them but I've never worked with epoxy. Any recommendations as which type/brand of epoxy to use? I am using butyl tape to bed the portlights.
All items with bedding need to be redone on a PM basis.

Agree the hard part is cleaning the old compound off .
We use Dolphinite , an ancient product that works well, and fits any size flange or base.
Scraped off easily with a chisel , wipes clean with most any solvent , and you are ready to reinstall. A bit of compound on the bolts or screws is easy to do.
A half hour job should not take a half a day, avoid 5200.
