I had four different spoiler on my 7th gen, testing
If genuine one it has two bolts and 3m tape so if you remove the spoiler you'll be left with two holes.
I got round the problem buy buying another black boot from salvage yard in the colour of my car for peanuts but you'll unfortunately struggle in white I'm afraid.
Options would be rubber bungs, weld and paint or mugen spoiler which I think is only one that'll cover the holes
It's not to remove and not replace, it's lifting in the middle so needs re taping, also needs painting as there is scratches on the too off someone ring grabbing it. So just wasn't sure if it was taped all the way across. Cheers though
