Hi all, I have a 2010 prius and had to have the windscreen replaced a year and a half ago due to a stone chip which cracked. When it was initially replaced I noticed that the rain sensor was hanging off so took it back (National windscreens here in the UK). They attached it back using some form of adhesive and put masking tape on it to hold it (which I left on for a day or so as advised) which lasted just over a year, and now it is hanging off again. I can't really find any information about this in terms of what to stick it back on with? I could take it back but if there is an easy solution or a particular kind of adhesive I can use to stick it back on with so I can repair again if needs be that would be my preferred option. Can anyone offer any pointers?
