How can I remove scratches caused by wiper blades on perspex screen?-

[Mike k]

Hello

I have some sweep marks on my windscreen caused by the blades which I thought was glass but a friend thinks its a Perspex 'type' material and I know want to polish them out- is there any suggestions for tools, materials and techniques ?

Any advice appreciated

thanks in advance

Mike

It really depends on how deep the scratches are but this kit is very good. I have used these products professionally and they work very well.

I have got some perspex polish from a motor accesory shop designed for cleaning rejuvnating car head light lens. This would be my first try. If scratches are still too deep then you must rub them out with fine wet and dry sand paper. This will get the deep scratches out but leave a lot of fine scratches which are then taken out with even finer wet and dry until your abrasive polish then smoother abrasive polish. It can be done. If you take alot of material out you may intoduce distortion into the window.
I did know a guy who made a living from doing aircraft perspex windows. Perhaps you can find one nearby. But rplacing the perspex might be cheaper. good luck olewill

Thanks very much indeed for the advice on technique William H all points noted except replacing the Perspex wont be cheaper as I was quoted over £1000 if I ever wanted to replace the windscreen eek!
I have gone for the Novus stuff and Meguires so thanks Mrplastic and MartynG.

Be aware that it may have an anti-UV coating, which you will be rubbing off.
So once you start, you may need to polish it increasingly frequently.
You can buy an awful lot of Perspex or even polycarbonate for £1k.

Not if it is shaped/formed you can't

I suppose that we would all assume it is a flat sheet if it has wipers on it? Apart from advice on trying to remove the scratches, it may help to say what type of boat it is or better still a picture. You could then also get advice on whether you could replace the screen as a DIY project, whether with a fresh sheet of acrylic or glass.

I found Plast-RX helped with both sprayhood plastic windows & perspex. Brasso is also mentioned as being good for getting rid of fogging on plastic...
