Had Perception's done last year, along with a lot of gel cost repair from 2 poor jobs done previously, a previous owner and an 'expert' . The installer used #4 screws between the glazing and edge of the recess with washers on them. He used the sikaflex and primer for adhesive. After the adhesive dried he removed them, taped the window and gel coat and caulked the gap covering the holes. Looks great, and so far dry.
