I have done all of the above, but "back then" (w-a-a-y back) I insisted that the tracks had to move, so I avoided the staple or glue-to-the-suspension method. Now that I have ripened and even started rotting a bit, I take a
mature attitude: I WILL NOT EVEN BUILD a static kit if the tracks cannot be made to move.
Try a product called E6000. Follow the directions, giving it time, and you should get good results. Also run a search for "E6000" using the search box up top right. There has been some helpful discussion of Shoo Goo and E6000.
