I agree with Minn. I do not like debonder. You will get it in places you don't want it. It will also make it hard to get the new parts to kick properly. You do not need a weak joint here. If during removal you destroy it then make a new doubler. I like to put my doublers on this way. I lay both parts top to top. As in both wing saddle areas facing each other. I then have to install them opposite. It keeps me from makeing 2 of the same side. I hope this helps.
