Badly grounded front spoiler on my jasper blue 02 C-sports coupe the other day.
I'm in Sussex. A contact at my dealer recommended a guy who deals with scuffs/paint chips.
This guys visited and has done a 1st class paint job rubbing down, filling, spraying with laquer. The bill was £60 and he refused any tip.
You'd never know the work had been done. The guys name is Mitch Bortnik "scuffs "n" stuff" 07850 048379 or 07753 227005.
