to cut out a bonded windscreen u need 1 of these
a cheesewire
and or
a cold knife
insert the cheesewire through the glue of the screen and saw away but make sure you remove any interior trim it might touch because its very easy to saw a lump out of the pillars or the dash
or just insert the coldknife round the edge of screen and pull
once the screen is cut out remove all the old glue with a razor blade or scraper from both the screen and the body. once its all removed apply windscreen glue primer.then get your windscreen glue this should come with a nozzle that has a V shape cut in it

so when you apply the glue with the nozzle at 90degrees to the screen it comes out in a vertical bead.Put your trims around the edge and the screen is ready to go back in again.
you can buy online from
Random windscreen tool place where i found the pictures
or look up your local charles pugh or laddaw winscreen supplies
its probably worth going to a scrap yard 1st and having a sneaky play on a screen that isnt your own
HTH
Made that sound easy
