The stuff from Dow is not suitable for use in boat building.

Not quite.

There are only 3-4 basic resin suppliers in the world.

Dow, Ciba-Geigy and Shell come to mind.

There may be another one or two.

Each of the major formulators works with typically only one resin supplier.

That's enough.

I know my suppliers are a Dow house.

They supply material to build more than one boat builder including me.
