I just did a bg80 at 24lbs string job on a racket and when the owner came to collect it he noticed a paint chip on the racket, inside of the frame, around the 8th hole/main ending knot. I did not notice the damage on getting the racket and do not have any recollection of chipping it while stringing (do not use string movers etc. any more, just cutting the string in a point and I always get it through). Owner says it must have been done during stringing as the racket was 'new'. It had been strung by the store when he bought it, so no factory string. What do you guys do in such a case. ? b.t.w I charged 10 euros including BG-80 string.
