Full Disclosure: I make Raincoat and Fogtech.
Thank you for the longer term report. I would like to post it on my website if OK with you?
Sure thing......go for it
Also, I have a report from the owner of Epicurean Riders that he puts Raincoat on all of his plastic, even his turn signals! He claims it keeps them cleaner much longer
I also have got into the habit of using it on my instrument faces (speedo, tach, and RID). It keeps them from getting water spots on them (which is a major pet peave of mine)
