I have inherited a contemporary Cartier ballpoint pen with what Cartier describe as a black "resin / composite" body. The composite is badly worn in the grip section - indeed, there is a small patch of bare metal showing through (I assume, the main structure of the pen. I wondered if anyone knows of a repairer who can either replace the grip section or fill and polish the worn section? Cartier stores are proving pretty useless in this regard! My technical skills are relatively useful, if anyone can point me towards a suitable repair technique. The pen is of great sentimental value and it would be nice to have it looking a tad better! Wishing you all a very pleasant weekend.
