Planalp UUMMmmmm… did you just say “Pop rivet the Velcro on” ??????
Yes, I, the self-proclaimed "Master Of The Half-Assed" have actually done this. Like I always say of most of my projects: "Laugh if you will, I don't blame you."
I wanted to listen to my iPod in my Tacoma but didn't want to pay $35 for some kind of cheap air vent/cup holder bracket. So, I took out my ash tray and made a metal bracket that mounted with the ash tray bolts: nice and solid.
I tried velcro on the bracket (after sanding and cleaning the metal for good adhesion) and on the back of a cheap case for the iPod. But, my vehicle sits in direct sunlight for hours at work and I found that when I'd pull the iPod loose, the hook part of the velcro on the bracket would just pull off with a slimey, heat-destroyed glue goo on the back. For some reason, the "loop" part never came loose from the plastic case, so for some reason the adhesion problem was with the metal bracket, not the iPod case itself.
So, I just put five pop rivets in the hook velcro patch that was attached to the bracket: one in each corner and one in the middle. Hasn't come loose since. I probably could have solved the problem with some higher-grade velcro with better glue, but I already had the rivets and the gun. The area the heads of the rivets took up, compared to the surface area of the patch itself, about 2" x 3" didn't affect the velcro bond. I suppose it would depend on the surface area of whatever size piece of velcro you're using and how many rivets were required.
I'm a big pop rivet guy: I use them all the time.
