I did it at home – looked ok but up close I had managed to get hairs, dust etc under it that I didn’t really notice when I put it on.
It was fine to love with – its a bike after all! But when some of the corners started to lift and got mud under them I ripped the whole kit off lol.
Then I just rode the bike, scratched it up – cried at first scratch, then got over it and added some more!!
I have not done it to my new bike. I tend to keep bikes long enough for any damage not to make a difference to the sale price.
