The lower side panels of my white Beomaster 6500 are partly coming loose. What's the recommended method to remove them completely in order to glue them on properly again? Iron above a soft cloth? Whilst the lower body of my BM5500 seems made of metal (knock test), the one of the 6500 seems a chipboard. Is that possible? Ok, I can only see some 2 cm of it... I will try to make some pictures tomorrow, if needed. Thanks! cc
