This is a great technique for reducing print through of structural fabric weaves in molded epoxy parts. It works by trapping extra epoxy between the fine weave and the structural plies the stiffness of the glass compared to resin minimizes the surface shrinkage reducing print through.
Our goal on a repair is to scarf in and replace structural layers one for one , same weight same direction, slightly below the surface. Any fairing required should be done with a similar resin chemistry filled with glass micro balloons to reduce the epoxy weight and facilitate easier sanding prior to paint.
Grams count our power to weight ratio is way less than your RC models and our repairs can be bigger. I appreciate your thoughts and methods for model repair. Most of our guidance on repairs goes back to Burt Rutan and his pioneering work on mold less composite structures.
