My
boat is on a
mooring in Spa Creek in
Annapolis. Last year it was a duck nesting in the
cockpit. This year is is spiders who have invaded my transom and
cockpit. There are broken webs wit lots of dead black flies streaming about. I know I can get rid of them with an insecticide. The problem I have is green spots all over the gel coat that are difficult to remove. I assume these come from the insects but they are not necessarily under the spider webs. Has anyone else seen this and what have you done about it?
