Many thanks all I shall try and get back.
I have two-one is defo not painted on it has a granular consistency in the red material "M" and has a sort of lug holding mech or system holding in place.
So as it was a scrap unit I tried all sorts to free it AND was unsuccessful.It destroyed most of the lip and edges and of course the logo.
I shall look seriously at the other, and report back.
My reason for wanting to remove the logos is that I have had a unit made on a 3d printer and want to transfer the logos onto it rather than art work or printing-well thats why-the how will take a lot more effort I suspect.
