Thanks for your reply. Is the reason for this factory

be if the tools
are good.

Anyway I was just curious if there was a secret competition
reason for
roughing the surface to keep the airflow attached longer
than a shiny
smooth surface would give.

Contrary to popular belief gel coat when it is removed
from the mould does not have a shiny mirror surface
that is why it has to be polished (sanded). Over time
the gel coat shrinks and you can often see the pattern
of the underlying glass layup.
