I appreciate all good thoughts on this.
I just finished doing what
James1549 suggested last night, and that was to scratch the side.
I took a single edge razor blade to it, thta coating is TOUGH!
The attached photos speak for them selves, it is like ZX2 Nick said "there is plenty of material visible"
They are not painted but coated with some kind of metallic substance.
Anyway, situation solved, thanks all for your 2 cents it was all good.
