Isn't that a Home depot rubber garage door seal.....
Just kidding, its an inside joke that you will come across if you search for spoilers, skirts and lips here eventually.
Amazingly some places have tried to sell the garage seals as cheap lips believe it or not!
I've been thinking of adding a lip as well and saw some nice ones on ebay.
No idea what that one is.
Seems like the rubbery type do better than fiberglass as the glass ones suffer more visible damage from stones, badly angled curbs etc.
Let us know what you find out about that one.
