Has anyone had problems with their pollycarb,Lexan windshields crazing.
I used to cover mine with a piece of air mattress, you know the one with the velour on one side.

In a matter of a couple of months my screen would be crazed so much you couldn't see through it.
I thought it might have been the spray and wipe i was using to clean it so I didn't use that stuff on the next one.

The next screen crazed up in no time, I kept going back to the supplyer but they couldn't offer any solution as to what was causing it other than fuel fumes because I cover the machine with a heavy rubber tarp but only after it has cooled down .

So three windsceens later and a shitload of money they gave me a piece of paper with what you can't put near the pollycarbonate.
On the list was plastics of any kind,so there was the culprit, the bloody plastic mattress.

I have had a new screen now for 4 months and no sign of crazing, it seems that plastics let off a vapour that attacks
the lexan.

I now cover the screen with a cotton sheet.
I hope this may save someone the frustration and expence I went through.

Bazza.

Also got to keep them clean,
Best way is to use Mr Sheen, and make sure you use it regularly, as the waxy layer stops the dirt from bonding to the screen.
To Clean it then use a very soft disposable paper towel.

Perhaps we could ask Geoff to start a Handy Hints Thread group. Cotton Liners and Mr Sheen would rate very well as a start. Thanks Bazza And Ross/

Under no circumstances should you go any where near Polycarbonate with Metho, it is a sure fire method of causing it to fracture .

Rotor

Is that a one piece elevator on your new project?

rotor

Yes, the one piece elevator is called a stabilator.
