Going to be replacing our bridgedeck deadlights. Ten total, approx 2’x2’ each. They are installed with adhesive and an inner border of spacer tape/gasket tape. Unsure of what the adhesive is but I’m assuming it’s one of the usual DowSil/SikaFlex glazing adhesives. Any tips or thoughts on how to remove them? Ideally I’d like them to come off in one piece since I was planning on using the old ones to template the replacements.
