Using the template to create the new shape. The pictures below show the steps in creating the guides usingepoxy thickened with Collodical Silica. Fairing filler will be used to fill in the rest. So when block sanding the Collodical Silica which is harder to sand then the fairing filler will retain the foil shape.
I will grind down the high spots created by the epoxy that was squeezed out from under the template.
