I need to add 3 coats of cloth to re-enforce the hull of my boat. I seem to
remember that one should NOT wait 24 hours between each application, or one
would have to sand/grind the surface to wax??? Is that correct, and what is
the best time to lay the second and third coats?

The area is about 4 x 4 inside of the hull, so I can pretty well time the
applications as I please. All help appreciated. Thanks RichG
