Re: How much Butyl tape is needed for one port light?
I bedded four rebuilt portlights with MaineSail's butyl tape after bedding the new plexiglass into the aluminum portlight frames with Dow 795.
Interestingly, we had a couple minor leaks in the first week and then I'm guessing the butyl tape slowly migrated into voids and then, no leaks.
I also rebedded all other deck fittings with butyl tape and with excellent weather-proofing results.
I am a believer.
