I had an identical scenario with my car. This came to light after a glass company replaced the windshield that was cracked. In the end I had the new screen taken out and re installed wih OEM seal at a very good body-shop here in London.
As the chap here was installing he explained that the seals make a big difference but as above its all about centering and positioning the screen. This guy did carefully clean out all the grooves and prior to putting in the screen explained he was going to use silicone as used on the 3.2 , 964/993 etc.....he said it helps as there is nearly always water ingress on the older cars. It does however make removal harder and the seal cant be re used.......Hope some this helps in so much as least you're not on your own with this !
