This is how we fix a rain sensor. Picture 1 shows you the bracket which the rain sensor attaches to on the windscreen. In the middle of the bracket you can see the old gel off the rain sensor its stuck on the old windscreen. Some people try and get the old gel off and stick it on the rain sensor but that never looks right and it doesnt work right. We use this liquid shown in picture 2. First thing is to put the sensor on a perfectly level surface, there are tools out there which help with this procedure, then slowly extrude the liquid on to the sensor, use the full amount in the chambers. Thats it, leave for 10 minutes and its dry enough, now fix on to the windscreen, good as new.
