I do believe the post about RainX and RainX wipers is somewhat misleading....

I'm not a fan of RainX but that's merely because I'm very picky about detailing products and prefer to use PPG Aquapel.

However, I'm sure there is a HUGE consumer market that uses RainX with whatever wipers they have on the car and it does its job without breaking down their wipers. It could have been a isolated incidence in your case but RainX is such a popular consumer item......I do believe something would have cropped up in the news, etc about it breaking down other brands of wiper blades if if was indeed the issue.

Just one mans opinion.............
