Thanks! Not a bad idea, but I should sand everything down anyway to remove the paint first, as it would not allow anything to stick correctly, so a combination of both would be best.

If your going the grinder route have someone lightly pouring water over it the whole time. Dont breathe the dust!

Yeah paint removal is probably necessary to get proper bounding of the layers. Maybe there is some kind of primer but that is dependent on the used paint.
