lol think that was my suggestion....
i've done it myself, easy job, just open the boot take the 3 little covers of and undo the nuts, mine was also bonded on, just give it a bit of force but be carefull not to damage the glass.
go to halfords and get a pack of the assorted grommits think the 9 mm one fill the holes perfectly, also get the pack with the larger ones in and do your rear wiper while your at it, (not sure if you have done this already?)
i did try to use the nut covers to plug the holes but it didnt look right to me, the grommits look much neater imo.
its all reversible and costs a couple of quid! nothing to lose
