Bedding, sealing fasteneres on new teak above deck

[Tatheelrod22]

I'm wondering if I'm somehow posting wrong, although I've posted in the past with no issues, but I posted the below yesterday and had no replies which I found strange, plus I noticed that my post title wasn't in bold like all the rest. Anyway, I'm trying again.
I'm about to install new teak on my boat. I have 4 new deck handrails, a cabin top eyebrow, and runners that hold sliding overhead companionway hatch in place, all ready to be installed on my boat. I've put three coats of clear epoxy on it all, have sanded it smooth, and once installed I'll put a minimum of 5 and probably 6 coats of varnish on. I plan to use Butyl tape under all of it. I read somewhere to put the screws in, then before installing the teak bungs, put clear epoxy over the screw heads to get an excellent seal. That makes sense, but aren't I inviting problems whenever any of it might be removed?

I've used buytl tape only once before on some cabin portals and it was a success and it definitely not messy and easy to trim afterwards, but those are vertical not horizontal installations.

Just looking for some voices of experience on this subject.

I think you are on the right track. I prefer butyl tape for bedding anything that uses mechanical fasteners for it's ease of use and longevity. I also use epoxy to seat teak bungs. Yes, it would be a pain to remove them at a later date, but not impossible and, hopefully, it will be done by the next owner.

I would "bed" everything in thickened epoxy, especially the handrails. It will greatly improve the strength, there will be no flexing and you won't end up with rot to the core. For the eyebrow and runners you might not even need screws. Just be sure to rough up the teak surface and rub several times with acetone to get the surface oil off and mask everything.
