My AVS rain guards are adhesive (3M) and you have to scotch pad the rubber, then use alcohol pads to clean them, and then install them, then WAIT 72 hours before rolling your windows down… It is all in the prep work…
My advise is go to Amazon and find the Amazon’s Choice or at least a set that has thousands of 4+ stars, my AVS (Auto Ventshade) has 8,049 4.5 stars from customer reviews…
Or go to a pro shop that sells and installs custom stuff and let them install them correctly…
