Posted on 08/03/2018 14:00 by greylagHaving had a close encounter with a narrow Welsh hedge lined lane, we now have some marks along the windows. Can they be DIY'd away or is there a professional out there waiting to do it for me?
Any info would be appreciated.

Used this Link on my previous and current caravan windows and well impressed. I had a very deep scratch on my front skylight and removed it completely with it. Only difficult bit was having to work off of a ladder
When my current caravan went back to have the water heater repaired they asked me what I had used on the windows as they looked like new.

I would seriously recommend that you use nothing but a polishing product specifically formulated to use on acrylic plastic windows.
Using many other products including glass and metal polishes presents a risk of a time delayed chemical attack that can leave the window with a nasty, irrecoverable, rash of micro crazing. These appear as whole number of minute silver glints in the affected areas.
What occurs is the chemicals used in those unsuitable polishes release the inevitable stresses locked up in the plastic from when the window was heat moulded. Alcohols and acetic acid which most metal and glass cleaners contain, along with other agents cause this.
As said this is not something that happens shortly after doing the job, it is an insidious chemical attack taking typically several weeks into months to reveal its affect.
Before saving a little of the price of buying the right stuff to safely do the job you best check what the replacement cost of these very expensive windows are before using anything else.
