reasonably easy to get them off - at least as far as the first foot or so of the front wheel arch (whilst I was trying to get the front grill off).
Pain in the butt to get them back on
and I gave up trying to get the grill / front valance off...
but that could just be me and my basic ineptitude...
personally, I'd take the easy option of lots of masking and spraying in place LOL
