Our drive is a bittight and, reversing
the motorhomein, Imust have
touched oneof the concrete fence
posts with the offsiderearwindow,
puttinga six-inchsetof deep
scratchesalong the middleof it. I’ve
been too upsettomention it earlier.
Browsingthrough the local
Halfords, I cameacross a promising-
lookingrepair kit fromAutoglym.
The kit is actually forrenovating
road-blasted plastic headlights, but
I thought I’d giveit a go onmypoor
window. The kit costs around £27
andcontainseverything youneedto

window.
There’s agreatvideo(by
Autoglym)that tells you exactly how

Followingthe kit instructions

carefully, I tookmytime withmyfirst

effort,but Ireckon you could repair a

badly scratched windowin about 30

minutestopswitha bitof practice.

This wouldalsoincluderemoving

anysurface scratches causedbythose

inevitable treebranches.

I reckonthe kit would begoodfor

another fivesimilar-sized windows, ie

Tomake the

Dometic window

easier to repair it

needs to be removed.

Start on the insideby

unscrewing theTorx

screws holding on the

catches and stays

3

Outside, lift the window up to

expose the endcap screw – this

needs to be removedbyusing a

Pozidrive screwdriver

4

After undoing this screw,the whole

window can be slid out along

its sliding hinge and removed from

the vehicle

5

Slide the window out of the

top channel until the whole

unit is freed – put it down on a

soft cloth on your workbench
