I just finished... are you serious... rain took it off?!? I know that I've used the same tape on my old bmw for an m3 trunk spoiler and it held up fine. I guess we'll see how it holds up tomorrow morning during my commute @ 70mph . I'll post up some pics tomorrow. (if they are still there )

 

Driver's side was still there,abd very solid,but I lost the pass,side.

 

Tape is fine. Silicone is fine too. I used 3 dots of silicone on my friend's RSX eyelids, and its like they are welded on.

 

these are on with tape and have been on for a couple years now- and they arent coming off unless i really work at them.
if i removed them i would have to use something to get the residue off...
i would not use razors on the lights- there are several products that would work (citrus based would be my first choice, but even wd-40 would help).
