What vinyls are these? Are they premium auto styling? Something looks iffy about them and it's not just the fact that only the face appears to be covered.
My suggestion; blue bat overlays + professional install if you don't feel up for it. Otherwise, a proper heat gun (or hot air gun for soldering) will help a LOT.
Here's a link to my tails, I LOVE them. Pretty much the only option I'm 100% sold on short of the Grazio tails.
