Galley ~ New portlight glass -
The portlights were leaking. In removing the portlights, it was
interesting to find that the some of the portlights had been
bedded and sealed with an assorted mixture of window glazing
compound, polysulfide and 3M-5200. It appeared that each layer
of goop was applied on top of the previous layer. It was
obviously a poor way of sealing the portlight to the hull and
flashing. Additionally, over the years, and owners, the type and
size of fasteners that were used on the portlights had evolved
so that very little was common or standardized. The portlights
showed years of accumulated paint and corrosion. The decision
was made to strip and refinish them.
The old portlight gasket material was removed. A high-speed wire
wheel was used to clean the accumulated paint and corrosion from
the portlight bolts, nuts, washers and dogs. The front and
backsides of the portlights including the aluminum portlight
dogs were sprayed with two coats of Rust-Oleum Red Primer. After
drying overnight, they were again sprayed with two coats of
Rust-Oleum Gloss White Appliance Spray Paint. The bolts, nuts
and the inside of the dogs were painted with Never-Seez grease.
New gasket was then fitted and secured with contact cement.
The backside of the portlight was heavily coated with 3M-4200
and the portlight inserted into the opening. The portlight was
then screwed back in place using 2" stainless steel screws.
Sixteen screws hold the portlight next to the seal. The new and
standardized screws were lightly screwed into the holes and
given a couple turns. It is important to let the caulking cure
for a day before tightening the portlight to the boat, and so,
the following day the screws were tightened down. |
