I work for a company within Certass and compile detailed reports for various DG insurance companies, my background is in the repair side of DG, anything from snapped handles and steamed units right through to invisible smart repairs, pvc reconstruction, painting, refoils, wax repairs and so on, i'm probably a bit more advanced than the usual plastic surgeon/DG doctor but i know what you meant.
While out of work i did try and go SE but got no help
