I would actually try double-sided tape. It's more similar to what Boss uses for the foot pad and skid pad than super glue. It's hard to say what the super glue would do to the rubber over a long period of time too.
double sised tape those boss pads are on there pretty tight i tried to pull one off a broken on and ripped the rubber double sised tape i wouldnt think would work ...anyone elses thoughts on this?
I have used Scotch brand doubke sided tape. It comes on a roll with yellow/black plaid in it. It is very similar to the tape they use for the top rubber. I've taken these off several times in order to repaint the boxes and used the tape to re-stick the rubber. It works 100%.
