The fitting of the windscreen was one of those tasks that I thought would be best left to a professional. One of the forum members had given a good feedback when their screen was installed by Howard of Merlin Motorscreens, based in Surrey.

Unfortunately I couldn’t arrange economic transportation of the rolling chassis to their workshop so it would have to be done in situ. As each car is different, I was warned that the installation may need to span over two days and that he may need to use his own supply of the rubber seals, depending on the quality of the SNG seals.

My only contribution to the whole process was to periodically returning to monitor progress and take a few photos of the various stages. On the positive side the SNG seals were useable. The whole area was protected with a generous covering of masking tape, the seals quickly trimmed to length and fitted to the windscreen flange using a bonding sealant.

In no time at all, the rubber seal had been lubricated with a soapy detergent allowing the screen to be eased into position from one side. A screwdriver was then used to get the final edge of the screen correctly seated into the seal. The next task was to tape the packing rubber strip to the top edge of the screen which sits between the screen and the top chrome finisher.

Re-chroming the top finisher can lead to distortion problems due to the heat created by the polishing process. Luckily my now banana shaped chrome finisher wasn’t too bad and he managed to tap it home with a rubber mallet.

At this stage you get the impression that the job is almost complete, but there was a lot more fiddly bits to do. There was much trial fitting of the A-post caps and chrome finisher to determine if and where additional packing rubber was required. The cavity under the rubber seal can be generous in places so additional rubber is pushed into these areas to avoid the screen dropping away from A-post caps later on.

A beading strip could now be inserted into the rubber seal. Its purpose is to push the external side of the seal hard against the windscreen and mounting flange, locking the screen in position.

The chrome finisher, running along the base of the screen to conceal the beading, slides into slots moulded in the screen seal. Although contact adhesive is also needed to keep it in place in the long term.

The A-post chromes are also bonded into place although they are also fixed by screws along their rear edge and slotted under the A-post cap at the top. The interior trim also slots under the cap and therefore needs to be fitted at the same time. The bottom of the interior trims are secured by the same clips used to fix the door cards.

This leads to the logistics conundrum of what should be fitted first …. the final adjusting of the wiper linkages needs the windscreen in but the dash top off, to provide access the linkages. Putting the windscreen in, included the fitting of the A-post trims. However with the A-post trims in situ, it’s then not possible to fit the dash top!!

All that remained was to trim back the top rubber strip inside and out and remove any excess adhesive with white spirits. From start to finish it took just over 5 hours. If anyone in the South East is looking for their screen to be fitted, I would thoroughly recommend contacting Merlin Motorscreens.
