thanks Daz thought I was - I always use a new blade but blue or black always seems to come off - perhaps I didnt explain very well - its not where its cut it is when I peel off the thin strip the strip actually seems to pull the paint off - have I stuck the decal down too hard before I trim it ??? I will see if I can get a better pic to show you allKev you are right in the trimming of the decal, maybe a brand new blade and not such a steep cutting angle.
Cheers Kev
