I sanded the paint off the patch and surrounding area and built up the area with epoxy resin and four layers of 1708 until the contour of the patch matched the surrounding area of the hull. The white spots are thickened eopxy under the glass, that I used to fill voids in the old repair (which will be removed from the top in the next step).
