Bill,
There's a number of German workers dying from cancer or already dead
from handling the Schwabbellack gel-coat that you refer to. The stuff
was toxic and it's good they discontinued it, good riddance.
Regarding trailers, the fiberglass shells are a case study in the very
limited life expectancy of the currently used coatings, they look
horrible after 10-15 years max unless kept indoors.

So what is different about the gel coats used in most pleasure boats and
the non toxic airplane gel coats? I see boats that are kept out in the sun
nearly year round, and with a couple waxings per year and a polish out every
few years, they seem very durable and good looking.
