I went to B&Q today and asked for Fablon, they have a rack of it by the wallpaper section.
I got a roll of Black for £7.58.
So i measured and cut out a section, it has a very helpful grid printed on the back of the backing paper to help you cut in straight lines.
I fitted it to my van, used an 11" deep piece to cover the centre dimpled dot section in the middle of the windscreen.
This is how i did it....
I cut a piece from the roll measuring 142cms long and 30cms deep and then offered this up to the windscreen.
Then i used masking tape to hold the strip in place and measures to make sure it was level.
I then cut the strip to shape around the top of windscreen using a stanley blade.
Then i sprayed the windscreen with soapy water, peeled off the backing paper and applied the strip to the windscreen.
You can then move the strip around because the soapy water prevents it from sticking to the windscreen.
Once i was happy with the correct positioh i used a plastic credit card type thingy to push out all of the bubbles and the excess water from under the strip.
Simples.
I also bough an LED display for the back on the van, when i have the dogs on board i drive a bit differently, i drive slower, take corners gentler etc etc, but because of this i always get some bell end up my chuff giving me the road rage, so i got a sign to explain....
