     Though I have been using West System's epoxy for the past several 
years, the Coho kit comes with System III epoxy. I want to add some of 
the west system additives such as colloidal silica etc to the system III. 
Does anyone foresee a compatibility problem doing this either presently 
or down the road?

Colloidal silica from West is inert with respect to S3 resins. Most additives
will work just fine. Just don't try mixing resins and hardeners from different
systems!

Kia Ora , I lost some of the reply's regarding adding wood flour etc.
 But my boat has a strip of between  4 " and 10 " wide (narrowes down at
the sharp ends)which has a mixture of resin and carbarundum flour(the
stuff grindstones and sandpaper are made of) .This protects the hull
from dragging over sand beaches.I have heard it mention that alluminium
oxide powder has also been used inplace of carbarundum.
