Nope will certainly require a re-spray (blended/frenched in or not). However, if they are blended/frenched in it is likley to cost a lot more to do as they have to spray a much bigger area. My rear spat got damaged last year (a quick fix if not blended as they just remove spat, repair, spray and re-fit - about £100 job). However because both rear spats were blended in (and remember only one was damaged) they had to crack off both spats, spray rear bumber because of this and then spray rear wings (and door and rear wings to roof also) to ensure a good clolour match. End result £1400 !! Glad i wasnt paying though as it was a non fault insurance job.
