The trim around my pop top (SCA 190 deluxe) has lost any grip it ever had on the edge of the pop top roof consequently hanging down when I raise the roof. It takes ages to put back each time I lower the roof. I have given the edge a good clean and tried to refit the trim with no success. I need to know how the trim is secured to the edge - is adhesive or mastic used or anything else or is it supposed to rely purely on friction?
