You may need to ask someone for a hand to lay the window in place, so you don't get sealant everywhere on the new screen. Lay it flat, and apply pressure to wet-out the sealant. Dpending on the sealant, it can take up to 2 days to completly dryso make sure there are no air leak spots, and it is thoroughly sealed.
1) The window film itself can be most any clear vinyl sheet used for tabletop covers etc. thickness is entirely up to you, genuine is approx 1mm thick. I chose a thinner sheet for a few reasons;
- Cheaper (2.50GBP), so I can replace it hundreds of times without killing the budget
- Better visibility, the thicker it gets the harder to see
A sheet measuring 1m by 50cm will be enough.
2) DO NOT ZIP THE WINDOW UP UNTIL IT HAS THOROUGHLY DRIED!! You will just rip the glue off, and have to start again!!
Uhhh! shouldn't you do that in reverse, get the material then hack the window apart?? doh! lol. Make sure you totally wet out the silicone sealer abpout and inch wide of the window and don't, and I mean don't touch it for 2 days maybe more till the glue is set, or you will just rip it out with the stress that the hood places on the back window, I know I did it!!
