I managed to secure the services of a UK trained Auto glazier to fit the screens to my S1 Sovereign ans thought I would document the process as it may assist someone.
Starting with a clean screen and aperture, removed of all old sealant, adhesive, rust etc, new seals and the original chrome. Apparently aftermarket chrome has very sharp edges,equally adept at slicing rubber and fingers , so beware.
Start with inserting the seal into the aperture, seating fully around the entire periphery, join at the bottom centre. Fit the screen into the groove in the lower part of the seal and progressively lever the lip over the edge of the screen using a putty tool ( a screwdriver with the sharp edges ground off will work) then move up to the top of the screen and do the same. Then work down the sides until the screen is secured into the seal
Check that the screen is located properly (ie centrally and fully seated) and then proceed to insert the filler strip. This locates into the groove in the seal and spreads the rubber outwards, securing it into the aperture.
Start at top centre, and work around the perimeter until you meet at the top centre again, trim to length. Make sure the filler is fully seated in the groove. Obviously a lot easier with the correct tool, but it can be done with a screwdriver or similar.
Next step is to fit the chome trim. Slide the trim into the lips on the seal and push across to the centre of the screen, levering the lips over the edges as you go, much as when fitting the glass
Do the same for the other half, and complete by fitting the joiner strips that cover the joint.
Total job took about 1 hr per screen.No sealant was deemed necessary with new seals. The front ones did not fit very well around the top corners because of the tight radius, and this was rectified by filling the gap with polyurethane which dries with a satin finish so is not too obvious.
Smoothed off before curing of course!![20200905_131126|666x500]
Finished product! Hope this is helpful.
