There was a slight depression in the leading edge root rib area on both sides of the horizontal stabiliser, so I scuffed the area one section at a time with 80 grit paper, wet with epoxy resin, then used a wooden screed to apply a thin layer of epoxy and Aerosil. I dabbed some mix into a few minor holes, which will all be sanded flat before a layer of Upol Reface.
