How long does it last on average? (Duragloss Rain Repel)
Are the wipers on the site just normal flat blades or anything special?

They are just flat blade. The best blades are the silicone ones. PIAA and XOPC (currently have these on my car) do some and these on their own give a rain X effect without applying any selant. They leave a thin layer of silicone on the windscreen and it works well.
As for products, the Carlack Glass sealant kit we do honestly lasts longer than Rain X. I've had nothing but positive reviews about it and is one of the better selling products.
had a thought, what happens when your windscreen freezes up and you need to scrape it? surely that will take the rain x coating off no?
