Well finally finished around the new windscreen (£140 fitted), got rid of the rubber seal. I'm pretty happy with it:
A lot of if comes down to windscreen replacement. They generally damage some area of paint, and don't do anything with it. Just slap a new screen in... It just lurks underneath, waiting to rot...Is this a problem on other vehicles? Or just German vans. VW buses had the same issue.
The plastic rope used for setting window screens might work as a filler or backer rod. It comes in various sizes.The only drawback there could be the joint size involved:
Phenoseal: Joint size should not exceed 1/4” wide x 1/4” deep. If joint depth exceeds 1/4", use backer rod material.
The string trimmer pieces to enhance drainage and WD40 spritzing seems to be working on the bottom of the 2006 windshield.Factory white paint is poor. Add in razor damage from the windshield replacement, and it gets bad quick. In addition the drains at the bottom plug up letting water sit in the bottom.
