Hello Tom, I recently fitted one. Taking it on and off is a 5 minute job once you know how. remove the knee trim panels to access the windscreen nuts lay a old curtain on the bonnet (or I use an old foam carry mat) remove the windscreen bolts I put the bottom of the windscreen frame in polythene freezer bags to protect the paint as I remove it. gently lift the windscreen off and lay it on he bonnet (on top of the carry mat) if you have a heated windscreen you will now need to deal with the wires that connect under the scuttle. For ease of fitting and removal, I cut these wires and fitted small bullet connectors. Bolt on the aeroscreen and enjoy...Redline and Caterham sell a useful retaining channel device, with captive nuts, so that you can take an aeroscreen on and off without removing the knee trim.
