Thats for both suggestions. I am using pactra rattle can on this so I could always grab a bottle and a brush to cover the screw heads. I will also give the test strips a try too. Ive always had the habit of scuffing the lexan before paint so that plus pactras adhesion promoter in the paint should hold pretty well. If my epoxy doesn't work I have your word on shoe goo to go by. Never hurts to test first!
