Leaving it in the water won't harm the gelcoat, but on my old beater which I
guess was left in the water for about 20 years, what happened is the gel
coat below the water line is a slightly lighter color than that above the
waterline. Algae stain I suppose but it goes a ways beneath the surface
(tried some 800 wet paper) so I'm just gonna leave it there. What I do now
that I've rubbed it all down, is clean it and wax it (3M wax) in the spring
.... well ok, my son get's that task. And if the boat was new, that's what
I'd do ... and work out last years little scratches in the process.

What can I do to protect the gel-coat, I leave my boat in the water all
summer, will this harm the exterior of the boat.
Any ideas appreciated.....
