Peel the rubber off and then stick the velcro to it, it's the only way to make it stick.

I used industrial strength velcro on my Dano pedals without peeling off the rubber, and they're holding fine.

nice, I wonder what's a better idea: A. to try and stick it to the rubber then when removing for selling, try and clean it with alcohol or something? or B. peel the rubber off and then stick the velcro and when selling, take the velcro off and stick the peel back or glue it down if needed ?
