    have you tried modeling clay?? you can cut it into long strips and it'll stick to just about any surface then you'll be able to build the flanges..

    Molding clay works but it is a little difficult to work with for someone with a little fiberglass experience. Go to Walmart or a craft store and get Foam Board. You will use that to make your flanges. You will also need a Hot Glue Gun in order to adhiere the foam board to your part. Once you completely lay your fiberglass on one side (8-10 layers) then you remove the foam board and start your mold release, PVA, and Gel Coat and lay the other side. I hope this helps. Oh, before I forget use a razor blade to cut the foam board.

    the way we do it takes only a few Min's,* *polish you mirror,then put masking tape on the back, sticky side* out
    if it is a mirror that you dont mind scuffing the paint on then put a small line of super glue the mirror before you stick your tape on

    then put another strip of masking tape (sticky to sticky) on it,so now you have the sticky side down,then stick your cardboard to the back of the tape.
