[W126 Coupe] trunk seal replacement questions

[Shayegan, Richard]

My trunk seal rubber being fairly new is still perfect, but like an
idiot when I installed it I did it backwards (i.e. the curve is concave
towards the inside of the trunk, not concave towards the outside of the
trunk). I left it cause it keeps water out, but obviously it doesn't
channel well so I'd like to fix this. Will it hold up to using 3m
adhesive remover or do I need to get a new seal? Also, what glue was it
again that everybody said to use? I remember it was made by 3m but I
forget which.
Thanks,
Richard
