Aquapel is a product that works like RainX window treatment, but it lasts MUCH longer.
It's WAY better than RainX. I had one application last almost whole year and it's very durable even through winter.
I think it was also sold before as STP Vision Blade but that is no longer available.
There are dealers that will apply Aquapel for you, but they usually charge $30 per application. The stuff can be bought for about $10 USD per one application size on ebay but I'm looking to order some within Canada. If not, I will just order some through a US ebay dealer.
