Windscreen Repair #2

[fatboyoz]

Dear All,
I have a slight wiper mark on my laminated windscreen. It is barely discernable when a fingernail is dragged across it. Any suggestions on how to get rid of the mark without replacing the 'screen?
Thanks,
Colin.

The local glass company should be able to polish it out for you.
Or sell you the powder to do it yourself. Cerium oxide from memory.

Cheers
Ralph.
