I know this belongs in the DIY section but I don't think many people would read this if I posted it there. I bought the Stillen rear window spoiler a while back and haven't been able to attach it securely with the crappy 3M tape that comes with it. Did some research and alot of of people have been using silicone window sealant as a surefire way of keeping it on. Before I start messing around with it I just wanted to ask if anyone here has done it and what specific brand of sealant is the best for this?
