I have the side scoops, and using the 3m tape they kept falling off (good thing noone took it overnight!)......anyone have any other techniques? I was thinking screws or rivits but you cant get to the back easily
My guess would be that you need to degrease the area, because wax is probably impeding the double-sided tape from working. (I won't even go into the issues presented by the mere fact that you are using double sided tape on your car. )
