I like the eyelids, it sets them apart from the stock looking front ends. All up painted they cost me about $60, I had them on my car for about 4 months until it went to Willowbank and they both flew off at 3/4 track. I was pissed off at the time, but i spose its pretty funny now. At 120mph the double sided tape is shit. Like it was mentioned above use sycaflex or silicone.
This a pic of my car with the eyelids, my opinion is it definately looks better.
