I routed one out that was installed with weld on, same issue as you
were explaining. Therefore I am not using weld on on my plane!! I
set the depth to match the window thickness, it made a big mess but
left a very nice and flat surface for the reinstall. BTW, we switched
to Sikaflex and have been very happy with it. YMMV.
