    Anyone ever polished their screen?

    Mines the original screen, with the number plate etched in to it by a bloke in B and Q car park, Bessimer Road, Cardiff; for my old man in 1981....so I'd like to avoid simply swapping it.

    There a couple of wiper scratches, some weld spatter and one bit looks like someone ran a flap wheel it....the wiper scratches are the only ones in drivers line of sight.


    Anyone polished theirs, what did you use? Any tips?

    I once bought a kit with cerium oxide and polishing pads while on pilgrimage to Trago Mills at Liskeard..
    It did a fair job of hiding scratches by filling fine scratches with the oxide which was melted into the glass by the polishing pad.

    But it involved turning deeper scratches into wider valleys with 2400 grade wet and dry that you polished smooth, that then cause optical distortion. Which can be harder to look through than scratched flat glass.

  8. Shake and Vac? Might not polish the glass, but will put the freshness back.
