Hey Nutsy,

I started out trying to grind out the epoxy tar coating on the bottom of
my boat last summer. After loading up the grit on a 1/2 dozen disc on
about a sguare foot of bottom I called it a day and turned it over to
the Yard to be pealed. A rotary grinder is hopeless.

I've seen (Younger men than me) do racing hulls with long board orbitals
do some beautiful finishes but its just to much work for me.

I'll ask you what size grit you used for the bottom of those boats you
say you've done?
