Got new fixed ports in yesterday.
Went fairly smoothly - Paul, I used your advice to hinge the
ports up on a few pieces of masking tape - worked perfectly. The
whole process was much easier than getting the old ports off and
repairing the mess.
In retrospect I'd have the plexi cut professionally next time. I
was easy to cut with a variable speed jig saw - but not as
straight as I'd like. Maybe I should have made a template. Plus
finishing the edges was a pain. Not as smooth as I'd like - but
stand back a few feet and they look fine.
I did spray the non-window portion of ports with Krylon Fusion
black - did a nice job of blacking out the window. That said when
the sun was low and shinning right on the window I could see right
through the plexi where it wasn't painted and see the blue epoxy
repair and the rough finish (just a 1/2 inch around the window
opening)
From the inside they look perfect - nice to be able to see
out!!!!

Hi Mark,
I installed new ports via VHB tape and Dow 795 using
Krylon Fusion to make a bonding mask. The link to my write up
is below. As already mentioned, the mask provides a nice
finished edge hiding the underlying tape and sealant. I don’t
recall the source, but I have read that the Krylon Fusion acts
like a bonding primer for the Dow 795 promoting adhesion. (Dow
actually sells a clear RTV primer, see Dow PR-1200 ) There are
reports from folks on sailing sites who have tested the bonding
with and without a Fusion mask, and they report no loss of
adhesion. That stated, if you go with a Fusion mask, then one
thin coat is all that is need and likely better than a thicker
coat. But to be honest, I think the greatest detriment to
adhesion are your fingers. Don’t touch the bonding surface, be
it Fusion paint or not. And just before inserting the port,
give the surface mounted area one last wipe down with isopropyl
and let dry.

Thanks for the
info - I was hoping I could get away with a rough
repair.
As for the paint - I've read (elsewhere I guess) that
it's a good idea to
rough fit the window, trace from the inside where the
opening is, then
strip away the paper cover for the section of window
that will be against
the cabin top and spray paint it black with Krylon
Fusion plastic paint.
The idea is to make sure the VBH tape and the 795 are
not visible through
the plexiglass. There was some question about the
adhesive qualities of the
Fusion paint - so I might test that on old plexiglass.
While my plexiglass is dark grey I still thought I might
be able to see
some of the - I'll have to test that too.
