i have a friend in my car club who used them, let me just copy and paste his post he made
ah here it is
Just to let you know guys, had my car 'fixed' by these guys yesterday morning, took 3 hours and the scratches, deep and not so deep have nearly COMPLETELY dissapeared!
Great result for a good price indeed, 10% off as an AA member too so came to £170 for everything, including pretty much completely respraying back bumper as well as everything else!"
Anyway, we hear of all these horror stories, just thought I'd stick up a positive one, thumbs up from me
