Nope, it was very easy.
think they used black skilaflex stuff origanly.
we used a plastic scraper (credit card) to remove most of it.
then just used a mix of WD40, Brake cleaner, soft rags and elbow grease to get the last few stubborn bits off.
no bodywork reqd - very happy with that. =]
Good to know, thanks! Might drop mine off and fit something different at some point
