Post subject:  Removing scratches on the windscreen

My windscreen has some light scratches from the windscreen wiper. Is it possible to polish them out? Has anyone done this successfully before?

I've used 1/2 a bottle of Autoglym glass polish but it's taking forever. :(
My screen was in an 850 before so the marks aren't even aligned with my wipers.

If you have the patience they will eventually come out but you can machine buff them aswell if you have some experience with machine buffing. you just have to make sure you have the right compound and as fine as you can get for glass and take your time :)

I do have a (new) Supercrappy buff, can I put the autoglym glass polish on the pad and use that?
This buff is only a toy, really. :lol:

It has been done befor, i used a big machine buff but aslong as you keep it wet with the glym stuff and use the right pad (super soft i think) then it should be ok just take your time.

hmm would be interesting to see if that trick actually works! I might have to check it out and do a test on a spare bit of glass i think! :D

Did you read the comments on that last you tube video? I think I'll try the glass polishing compound and elbow grease.

There are various kits available to do it. They usually have a felt bob that goes into a small drill and cerium oxide powder. Cerium Oxide is known as lens maker's rouge, its probably the most appropriate abrasive for polishing glass. I've used it by hand and it does improve shallow hazy scratches. With a machine (and patience) you should be able to get it pretty good.

Here's one example of a kit.

Buffing pad on electric drill and lots of patience with Silvo polish (for silverware).

Polished out deep gouges in a windscreen for my son's first Mini - NOT noticeable from outside and only a little wavy from the inside depending on the angle. It took awhile....

Do NOT polish tempered glass in door or rear quarter windows. Tinkle!

Our front windscreens in most Oz Minis (except Cooper S which got Triplex laminated) were/are still tempered glass. So is there a problem polishing scratches out of these then? :?

I would be guessing so! Ours were laminated in the 70s.

You sure???

We have a 74 S & 75 Clubman...neither have Laminated Windscreens [doesn't prove year of change to Laminated though...could be from the wreckers] :)
