The zinnobar red paintwork of my 320 is mostly good except for a small area on one of the doors, just between the bottom of the window and the door handle, which has turned a shade of milky red/pink.
I tried to cut back the oxidised paint by hand, using Farecla G6 (as recommended in a Total BMW article on paint restoration), but there seems to be a hard outer layer of old polish or something that prevents the compound from getting close to the paint!
What should I do?
Thanks in advance as always.
