Now with the flat sides of your retainers facing upwards, if everything looks like it is where you want it, screw or clamp the retainers down pretty tight. This should allow you to check the fit of the rubber you will see on the outside of the sunroof, push them into place and making sure the seal is almost perfectly flat. Allow it to set then apply a second amout of glue, this can be sanded later to give a much better finish. I am sorry this is a long drawn out thread today.
