[Rhodes22-list] Portlight re-sealing

[Joe Dempsey]

Graham is correct. The portlites used are Beckson Fixed Port PF410-BS-20 (4"
x 10" x 2") I had to replace one (Don't use acetone to clean polycarbonate!)
and found it at Defender. Here are my notes from my Projects Report:

5.	Port Lite Re-Bedding
Port lites are a common source for cabin leaks which lead to interior damage
and headaches. There are almost as many instructions on replacing/rebedding
a port lite as there are occurrences! (“Practical Sailor Magazine” has some
great instructions online) I won’t go into the specific details of this
operation, but a couple of things I learned. My lites had been rebedded with
silicone sealer at some point. Again, there are pros and cons. One of the
cons I can attest to is the removal of silicone residue. It’s a bitch! But I
have found that Marine Formula by De-Bond Corporation will turn the residue
of just about any sealant/adhesive, including polysulfides (5200), into a
mush that can be easily removed with a putty knife, chisel or razor window
scraper.  Nonetheless, silicone sealant seems to be the best route due to
its adhesiveness, flexibility and waterproof properties. So that’s what I
used
Another thing I found out is that Acetone will ruin acrylic port lites!
Don’t use it!
