For my case, even after 3 days, after I removed the cover strip, I can still remove the excess E6000 residual by rubbing them with my thumb...end up like a roll of nose drop.
I used the cutter to carefully cut away the dried E6000 before comfortably stripping away. There may be scars but wont damage the other areas or crack the armor.
I too apply some tapes over the cover strip before putting on the clamps which will reduce the risk of it shifting. Watch it for a period of time just to make sure the bugger dont give you another slip up.
