Yes I have the same problem with you Moab_dan,
I guess it is because of the sun exposure (I live in the tropics)
Don't try to use (because I ruined the MB tex):
1. rubber glue, because it can't stand the pulling of the MBtex, so it will peel back.
2. super glue, because it will hardened the MB tex.
So, up to now, I am still want to know if anybody have successfully do this.
