It also works great on certain trim pieces "side marker bezels emblems ect" if you dont want certain pieces marking the paint.Its thin enough to be nearly unseen.
Ive redone a few on my chevelle buy some neoprene rubber.Its sold by the foot" usually at 3 foot wide" I would buy it 1/32 thick It comes in different thickness but 1/32 is perfect so its flexable enough.It works great & was really cheap.I bought mine at an industrial hardware store drill out the rivets, Its a" full" piece of rubber then cut your piece punch out the holes for the rivets & re-rivet
I just sent my 69 chevelle rearview mirror &vanity mirror to a guy in Illinois.Have not gotten it back yet so cant tell about the work. Silver Service,16120 Vandustrial Ln. South Holland,Illinois 60473 Tel 708-331-5501 I believe he quoted me $15 a piece.
