Following on from this thread
I thought I would have a go at removing some of the wiper scratch,s from my wifes Car,s windscreen.
I bought 100g of Cerium Oxide and some 75m/m dia felt pads.
Both can be bought off Ebay, either separately or in a kit.
I mixed the Cerium Oxide with water in a small plastic bottle. I mixed it a bit thinner than car polish.
Then with my Porta Cable DA polisher I put the felt pad onto the backing plate.
I masked off all the area,s I did not want the Cerium Oxide to go on. ( I don,t think it will hurt the paint or plastic. But it just makes a mess if it gets flicked every where).
I poured some of the mixture onto the screen.
Then with the DA on speed 4 (too high and the stuff goes all over the place, hence the masking off).
With very heavy presure I went up and down the screen, then side to side. Untill the compound had dried out.
I wiped off the dried powder ( heck it does make a mess).
Then I repeated the procedure.
It is very hard work. Harder than polishing the paint.
This is the second time I have polished the screen with the Cerium Oxide.
The scratch,s are slowly coming out. You can see an improvement. But it
looks like I need to go over it again another day.
If you are thinking of doing this yourself.
It is not an easy job,(phyisicaly hard work) you will not do it by hand alone, some form of machine will be needed, an electric drill would do.( with the apropriate attatchments)
I also suggest you wash the screen first, then when you have done with the polishing, you will need to wash the car, make sure none of the residue block the drain holes by the pollen filter.
