How should I thicken the Forton for hollow-casting?
A. When you are hollow-casting in Forton, you can use cabosil to thicken the Forton for the “face coat” (first layer of material laid-up against the interior of the mold) so that it isn’t too runny when you brush it into the mold. Or you can achieve the same thickening by adding accelerator. For details on accelerator use, please refer to the Forton instructions.
